The Copic Multiliner 0.03mm is just downright cool! Marianne from I Like Markers sent me this sample to try out, and mentioned that this is the world's finest tip pen - I sure haven't heard of or seen anything smaller. What is impressive about it is that it doesn't feel too fragile when writing with it. I have used other micro tip pens, like the Pilot 0.05mm Drawing Pen, and I could hardly use it because I thought I was going to ruin the tip. I don't get any of that feeling with this Copic. Quite Impressive.
I meant to add a coin or a ruler to the photo to relate the size better, but hopefully you can tell with the pen included. It is a standard size pen, and the paper is Doane of course.
