Uni-ball have been creating a wide range of products for over a century. The POSCA range offer something for everyone when it comes to Arts & Crafts, from the full blown artist to the occasional hobbyist. The POSCA PC-5M Marker has a medium bullet tip that will produce a 2.5mm line.

These markers have long been a popular choice with Uni customers & have had continued success since 1983, so much so that they have a web site dedicated to POSCA. If you pay a visit you can expect to find news, competitions & a host of creative workshops. There are instructions for homemade magnets, kites, paper mice & much more, all designed to help everyone get the most out of the range.

The POSCA PC-5M are a multi purpose water based paint marker with pigment ink. There are diagrams on the side of the pen to get you started. Once I removed the plastic it took a while for the paint to emerge, I guess I got a little impatient as I made the mistake of shaking the pen vigorously without replacing the lid! The inevitable happened & paint went everywhere, this did however give me the chance to test the non-permanent claim.

I can report that the series of bright blue dots was easily removed from my hands & desk, it also came out of my clothing after a spin in the washing machine.


  • Write on most surfaces including fabric, glass & metal
  • The ink doesn’t seep through paper
  • Non-permanent therefore easily removed
  • Resistant to fading & water
  • Odour free
  • Useful for scrap booking, interior design, graffiti artists & architects. These versatile markers can be used for almost anything.

The POSCA PC-5M is available in a wide range of vivid colours, 33 to be precise.
