Posca markers for art therapists are opaque, water-based paint pens that give a practitioner controlled colour, clean lines and tidy storage across individual and group sessions. This guide covers which tips to stock, how to build a session kit, and how to keep it organised.
- Start with a PC-5M medium bullet tip set: it covers most session work on paper and card.
- Add PC-3M or PC-1MR fine tips for detail, lettering and outlines.
- Choose POSCA wallets or bundles for your colour selection, then store the markers in a counted case.
- Free bulk quotes are available for orders across several rooms.
Why Posca markers suit art therapy practice
Choose defined tip sizes for the tasks you plan, with colours you can count out and pack away between sessions.
Start with a PC-5M medium set and add PC-3M fine markers for detail.
This guide makes no claims about clinical outcomes. It covers the materials side only: tips, colours, surfaces, storage and budget. Your own practice and site policies decide what goes into a session.
How to build a Posca kit for art therapy sessions
Start with a medium tip
The POSCA PC-5M medium bullet tip suits bold lines and filled shapes.
- Use it for outlines, fills, patterns and mark-making.
- It is forgiving: the tip is firm and the line stays consistent.
- Buy a wallet or a gift tin rather than single markers so the colours match across the kit.
- Keep two or three duplicates of your most-used colours, usually black and white.
Add a fine tip for detail
The POSCA PC-3M fine bullet tip suits lettering, patterns and detail alongside PC-5M fills.
For even finer lines, the PC-1MR has an ultra fine 0.7mm tip. See the POSCA PC-1MR for single markers.
- PC-3M suits detail without losing colour strength.
- PC-1MR suits outlines, small lettering and fine pattern work.
- Fine tips are slower to fill large areas, so keep them as a supporting set, not the main kit.
- Match fine-tip colours to your medium set so clients can move between sizes.
Choose a colour range that fits the room
Choose a full colour range or a themed wallet for a narrower palette.
- The full PC-5M range comes as a bundle of 57 colours.
- Wallets of 8 are easier to hand out and count.
- Themed sets include Warm Sunset, Aussie Spirit and Portrait colour tones, all in the PC-5M medium tip.
- Pastel wallets in PC-3M and PC-5M suit softer palettes.
Match the marker to the surface
Posca markers work on paper, card, wood and canvas. Most session work happens on paper, so start there.
- Use heavier cartridge paper in a visual art diary for sessions that run across weeks.
- Use card for work a client takes away.
- Use wooden shapes or small canvases for longer projects.
- Test a new surface with one marker before handing out a whole set.
- Keep a scrap sheet at each seat for starting tips and trying colours.
Prepare and care for the tips
- Shake each marker with the cap on before first use.
- Press the tip down on scrap paper until the paint flows.
- Cap every marker straight after use.
- Wipe the tip if colours mix, then press on scrap to clear it.
- Replace a worn tip marker rather than forcing it.
Set up storage and tidy-up
A counted case makes setup and pack-down quick. Choose a small or large POSCA storage case, with or without markers.
- A small case kit holds 24 markers, suited to a one-to-one room.
- Large cases hold up to 60 markers for group work.
- An empty large case lets you fill it with your own choice of sets.
- Count markers out at the start and in at the end.
- Keep tips and spare caps together so nothing goes missing.
Plan the budget for groups and terms
Choose a bundle for its colour selection, or singles to replace particular colours. PoscART offers free bulk quotes for larger quantities.
- Set a kit budget per room, then top up each term.
- Order wallets for the room and a bundle for the cupboard.
- Ask for a bulk quote if you equip several rooms at once.
- Keep one backup set sealed.

FAQ
Which POSCA marker size suits an art therapy kit?
The PC-5M medium bullet tip is a practical starting size. It handles outlines, fills and mark-making, and a PC-3M fine set covers detail alongside it.
How many Posca colours does a therapy room need?
A wallet of 8 to a set of 20 covers most one-to-one rooms. Group rooms often add a larger bundle so every client has a full choice.
Do Posca markers work on paper?
Yes. Posca markers work on paper, card, wood and canvas. Test a new surface with one marker first, and keep scrap paper at each seat.
Should I buy single markers or sets?
Sets are easier to count and keep colours consistent. Buy singles only to replace a worn tip or top up a favourite colour.
Can I buy Posca markers in bulk for several rooms?
Yes. Free bulk quotes are available for larger orders across several rooms.
How do I stop markers going missing in group sessions?
Use a storage case with a fixed number of slots, and count markers out and back in each session. Keep spare caps in the case.
One last thing
Keep spares of the colours your practice uses most. Check the kit before reordering rather than replacing every colour at once.
