Common questions
Everything people ask us about POSCA before they buy.
Yes, on most sizes. Pull the old nib out with tweezers and push the new one in, then shake the pen with the cap on and re-prime on scrap paper. A new nib costs a fraction of a new pen.
The PC-3M and PC-5M nibs are — a fresh bullet at one end and a chisel edge at the other, so you can flip one over before you replace it.
Usually not. It happens when you work over paint that was not quite dry. Press the pen on scrap paper until its own colour comes back through, or pull the tip, rinse it under warm water, dry it and refit.
Often, yes. First try reviving the old tip: pull it out with tweezers, soak it in warm water until the dried paint releases, squeeze it out and let it dry before refitting. If the tip is past saving, a replacement nib brings the pen back.
Cap on firmly, stored away from heat and direct sun. Brush tips are best kept flat so the paint stays evenly through the fibres; everything else is happy standing up. Cases and storage.
