Suited to flowing brush lettering: POSCA PCF-350. Suited to controlled brush marks: POSCA PC-5BR. Suited to fine outlines, everyday shapes and broad lettering: POSCA PC-3M, PC-5M and PC-8K respectively. This guide compares art markers PoscART sells, with tip sizes, pack formats and uses taken from their product pages.
- POSCA PCF-350 art markers have a soft 3–10mm brush tip; choose singles or the 10-colour bundle.
- POSCA PC-5BR has a firmer 1–4mm brush tip, with wallets of 4, 8, 16 and a 60-pack.
- POSCA PC-3M suits fine opaque detail; POSCA PC-5M suits everyday shapes and mixed-media accents.
- POSCA PC-8K has an 8mm chisel tip for broad graphic shapes and lettering.
- Blend POSCA brush paint while wet; let it dry before layering distinct colour and details.
Why this matters
A flowing letter and a small outlined motif call for different tips. POSCA brush markers change line width with pressure, while bullet tips support more consistent outlines and chisel tips provide broad faces for lettering and coverage.
Choose the mark before the colour set. A larger collection does not correct a mismatch between the tip and the job. If your artwork combines lettering, small details and filled shapes, give each task a suitable format rather than expecting one nib to do everything.
The products here use water-based POSCA paint. The comparison is about brush feel, stroke width and working scale, not a ranking of retailers or a recommendation to buy another type of marker.
How to choose art markers
- Brush feel: POSCA PCF-350 has a soft brush; POSCA PC-5BR has a firmer, semi-flexible brush. Choose the feel around your lettering or illustration task.
- Line width: PCF-350 covers 3–10mm and PC-5BR covers 1–4mm depending on pressure. PC-3M draws 0.9–1.3mm lines, PC-5M draws 1.8–2.5mm lines and PC-8K has an 8mm chisel tip.
- Paint behaviour: The brush-marker product pages describe water-based, matte, opaque paint. Wet colours can be worked together; dried colour supports subsequent layers.
- Surface response: Match the marker to the paper, canvas, wood or other project surface described on its product page. Test the combination you will actually use.
- Palette usefulness: Start with the colours your subject needs, then choose singles, a wallet or a bundle.
- Working scale: Fine bullet tips suit small detail; brush tips vary width within a stroke; the broad chisel tip suits larger graphic areas.
A useful set supports your drawing habits rather than asking you to change them. For small outlined shapes, a fine bullet or firmer brush adds more control than a wide, soft brush.
Art markers at a glance
The order below follows distinct drawing tasks. Use the “Suited to” column as your starting point; pack quantity changes the palette or shared supply, not the tip specification.
| POSCA marker | Suited to | Standout feature | Key limitation |
|---|---|---|---|
| POSCA PCF-350 | Flowing brush lettering and loose illustration | Soft 3–10mm brush tip; singles and a 10-colour bundle | Wider soft strokes are not the choice for miniature outlines |
| POSCA PC-5BR | Controlled brush lettering and layered illustration | Firmer 1–4mm semi-flexible brush; wallets of 4, 8, 16 and a 60-pack | Pressure changes stroke width, unlike a firm bullet tip |
| POSCA PC-3M | Detailed opaque drawing | 0.9–1.3mm fine bullet tip | Slow for covering large backgrounds |
| POSCA PC-5M | Everyday mixed-media accents | 1.8–2.5mm medium bullet tip | Too broad for the smallest details |
| POSCA PC-8K | Broad graphic shapes and lettering | 8mm chisel tip | Less suited to miniature work |
1. POSCA PCF-350: suited to flowing brush lettering
POSCA PCF-350 has a soft brush tip with a 3–10mm stroke range depending on pressure. Light pressure gives a narrower line; firmer pressure produces a wider sweep. Its product page lists calligraphy, colouring, expressive outlines and illustration among its uses.
The paint is water-based, matte and opaque. For softer transitions, the product page describes softening wet paint with a damp brush. Work while the paint is wet rather than expecting a dried painted layer to behave like fresh paint.
POSCA PCF-350 pros:
- Soft brush tip changes width through pressure.
- The 3–10mm range supports flowing letters and broader strokes.
- Singles let you choose individual colours.
- The 10-colour bundle contains one of every PCF-350 colour PoscART carries.
POSCA PCF-350 limitations:
- A soft, wide brush is less suited to small, uniform outlines than a fine bullet tip.
- The 10-colour bundle has a defined palette, not an unlimited colour selection.
- The product page specifies flat storage, unlike upright storage used for some other tip formats.
Suited to: Calligraphy, flowing thick-to-thin lettering and loose illustration with an opaque paint finish.
Choose a single PCF-350 when one colour meets your project brief. Choose the 10-colour bundle when you want the complete stocked PCF-350 palette in the same tip format. Store the markers flat with their caps firmly on.
Verdict: Choose POSCA PCF-350 for a soft, wider brush stroke; skip it as your only marker for miniature detail.
2. POSCA PC-5BR: suited to controlled brush marks
POSCA PC-5BR has a firmer, semi-flexible brush tip with a 1–4mm stroke range. Press lightly for a fine line and harder for a broader stroke. Its product pages describe lettering at card and journal scale, illustration, shading and layered colour.
The paint is water-based, matte and opaque. Colours layer once dry, and the semi-flexible tip is reversible. This gives you a different drawing feel from the softer, wider PCF-350 without changing to another paint type.
POSCA PC-5BR pros:
- Firmer brush tip supports controlled variable-width marks.
- The 1–4mm range suits smaller lettering and illustration.
- Wallets of 4, 8 and 16 offer different palette sizes with the same tip format.
- The 60-pack provides repeated colours for shared use rather than 60 different colours.
POSCA PC-5BR limitations:
- Stroke width varies with pressure, so it does not produce the same feel as a firm bullet tip.
- Its 4mm maximum is narrower than the PCF-350’s 10mm maximum.
- A bulk pack adds repeated markers, not a larger unique-colour range.
Suited to: Card and journal lettering, controlled brush illustration and layered colour on paper, canvas and wood.
Choose a PC-5BR pack for the job
- Wallet of 4: Four assorted classic colours for trying the brush format or keeping a compact palette.
- Wallet of 8: Eight assorted classic colours for lettering practice and illustration with a wider palette.
- Wallet of 16: Sixteen assorted classic colours for one artist working across layered colour and shading.
- 60-pack: A boxed shared supply containing 16 colours: six white, six black and three of each remaining colour. It is a bundle box, not a retail display stand.
All these packs use the PC-5BR’s 1–4mm semi-flexible brush tip. The 60-pack suits art departments, studios and workshops needing repeated colours; it is not necessary for a single project that needs only a few shades.
Verdict: Choose POSCA PC-5BR for a firmer, narrower brush; choose the pack size around the palette and number of users.
3. POSCA PC-3M: suited to detailed opaque drawing
POSCA PC-3M is a water-based paint marker with a 0.9–1.3mm fine bullet tip. Its product page describes line work, small fills, mid-weight outlines and decorative details.
Choose POSCA PC-3M when you want a controlled mark to remain visually distinct. For mixed media, test it over your dried background before drawing the final details.
POSCA PC-3M pros:
- Fine bullet tip suits controlled outlines and small filled shapes.
- Matte, opaque paint supports distinct accents.
- A firm tip offers a different drawing feel from a flexible brush.
- The tip is reversible and takes a PCR3 replacement nib.
POSCA PC-3M limitations:
- Fine strokes take longer to cover broad areas.
- Small gaps still need room for the 0.9–1.3mm stroke.
- A bullet tip does not give the same pressure-led movement as a brush.
Suited to: Small graphic illustrations, decorative outlines and detailed opaque accents.
Start with the actual scale of your drawing. If lettering counters and spaces between lines are small, test whether the nib leaves enough room before committing to the full composition.
Verdict: Choose POSCA PC-3M for controlled opaque detail; skip it as your only marker for large filled backgrounds.
4. POSCA PC-5M: suited to everyday mixed-media accents
POSCA PC-5M uses a 1.8–2.5mm medium bullet tip. It suits outlines and moderate-sized filled shapes without moving straight to a broad chisel nib.
Use POSCA PC-5M when the same drawing needs both an outline and a coloured shape. Its product page describes paper, cardboard, fabric, rocks, wood, pots and canvas among its uses.
POSCA PC-5M pros:
- Medium bullet tip balances line work and filling.
- Matte, opaque paint suits graphic accents.
- Rounded tip supports curves without a chisel-edge angle.
- The reversible tip takes a PCR5 replacement nib.
POSCA PC-5M limitations:
- Medium strokes can crowd small lettering and miniature details.
- Broad backgrounds require more strokes than a wider tip.
- Surface preparation and finishing depend on the material.
Suited to: Ordinary-sized shapes, outlines and mixed-media accents.
Choose POSCA PC-5M when most marks are neither miniature nor very broad. Add another tip when a recurring task shows what the medium tip cannot comfortably do.
Verdict: Choose POSCA PC-5M for everyday opaque shapes; choose a specialist tip when very fine or very broad marks dominate.
5. POSCA PC-8K: suited to broad graphic shapes
POSCA PC-8K has an 8mm chisel tip. Turn the edge for a thinner line or lay it flat for a wide stroke, as described on its product page.
Choose POSCA PC-8K for broad lettering, graphic patterns and larger colour areas. Its advantage is scale, not miniature-detail control.
POSCA PC-8K pros:
- Broad chisel face covers larger areas.
- Changing the nib angle varies the mark.
- The product page lists curves, coverage and headline lettering as uses.
POSCA PC-8K limitations:
- Small gaps are harder to control with a broad face.
- Nib angle affects the shape of the mark.
- Fine finishing work calls for a smaller tip.
Suited to: Broad lettering, fills and graphic artwork with room for an 8mm stroke.
Practise the lettering at its intended size. A chisel nib that works comfortably on a large heading can overwhelm the same letterform reduced to a small caption.
Verdict: Choose POSCA PC-8K for broad graphic work; skip it as your first choice for miniature drawing.
Match your markers to the surface
Your paper or craft surface affects the result as much as the tip. Test the combination you will actually use, including any painted or collaged layer underneath.
- Paper and card: Compare a small outline, a filled shape and a pressure-led brush stroke on your intended sheet.
- Painted collage: Let the underlying layer dry before adding distinct accents.
- Wood and canvas: The brush-marker pages describe illustration and layered colour on these surfaces.
- Fabric: The brush-marker pages list fabric as compatible, but preparation, fixing and a material test still matter. Do not treat compatibility as a promise of wash-proof results.
The PCF-350 and PC-5BR product pages list porous surfaces including paper, cardboard, wood, stone and fabric. On smooth non-porous surfaces such as glass, glazed ceramic and PVC, paint remains erasable until fixed. Use preparation and finishing appropriate to the specific material.
Choose sets after choosing the tip
The PCF-350 bundle provides 10 soft-brush colours; the PC-5BR wallet provides 16 firmer-brush colours. The PC-3M bundle and PC-5M gift tin support fine and medium bullet-tip work instead.
How these picks were organised
The recommendations match each stocked POSCA format to tip feel, stroke width, paint behaviour and working scale. They are use-case recommendations, not a scored product test or a retailer comparison.
PCF-350 covers soft brush work; PC-5BR covers firmer brush marks; PC-3M covers fine bullet detail; PC-5M covers medium bullet shapes; PC-8K covers broad chisel work. Pack sizes are treated separately from these drawing tasks.
Which art markers should you choose?
Start with POSCA PC-5M for ordinary-sized opaque shapes and outlines. Choose POSCA PC-3M when fine detail dominates, or POSCA PC-8K when broad lettering and coverage are central.
For brush work, choose POSCA PCF-350 for the softer 3–10mm stroke and POSCA PC-5BR for the firmer 1–4mm stroke. A PCF-350 single or PC-5BR wallet of 4 keeps the first trial focused; the larger packs expand your palette or shared supply.

Which PC-5BR packs are available?
PC-5BR comes in wallets of 4, 8 and 16 assorted colours and a boxed 60-pack. The 60-pack contains 16 colours with repeated markers, not 60 different shades.
Can I blend POSCA brush paint with water?
The PCF-350 and PC-5BR product pages describe blending while the paint is wet. Work wet colours together or soften a wet edge with a damp brush; let paint dry before adding distinct layers.

Store PCF-350 and PC-5BR flat with their caps firmly on, away from heat and direct sun. Their product pages specify flat storage for the brush tips.
Is the PC-5BR 60-pack a display stand?
No. The 60-pack arrives in a bundle box, with six white markers, six black markers and three of each of the other 14 colours. It suits shared art supplies rather than a single artist needing one of each shade.
One last thing
Test the smallest shape in your drawing, not just a straight line. A marker can produce a pleasing stroke yet still fill the gaps inside small lettering or crowd a patterned detail.
Draw that difficult shape on your intended surface before starting the finished piece. This trial reveals whether you need a finer bullet tip, a firmer brush or more room around the mark.
