How to use Posca Pens:

The Posca Paint markers contain opaque, fluid paint that is quite similar to acrylic paint. Even light colours can be painted on darker shades without loosing their effect. Colours can also be blended, with your fingers or with brushes. For a watercolour effect, work with wet brushes.

The markers all have water based ink, that’s non-toxic, therefore you can use them on your skin if you prefer, as well as suitable for children’s use.

The paint dries very quickly, but required a few minutes on less porous surfaces. They are also permanent, or can be made permanent on all surfaces.

Available sizes and tips

The Posca Pens are not refillable, but it’s possible to change the tips. PC-1M, PC-3M, PC-5M, PC-8K and PC-17K have replaceable tips, but generally they all can be reversed.
If the tip dries, it can be simply taken out by pulling and rinsed with water.
