I purchased the POSCA in an attempt to find my holy grail- a white brush pen. Unfortunately, the POSCA has a lot of issues that prevent it from being such. 1. The ink is watery, and will reactivate non-water-safe ink if applied on top (very important if you're a comic artist, and are using the white brushpen to make corrections) 2. The ink isn't fully opaque, so even if it does not reactivate the ink beneath it, there will be some ghosting 3. The pen is pressurized, and may leak during barometric pressure shifts (or in an airplane cabin). Unfortunately, I do not reccommend this product.

True the ink of this Posca pen is a little thin. but it allows for layering. Since I know how this pen acts I love it. the attributes allow for some very cool techniques that can't be accomplished with other paint pens I've used. Also it doesnt smell and allows you to layer without pulling up the line you just layed down. if you are looking for a white pen try this. If you are expecting white paint try a tube and a brush.

This is my first time using Posca Markers. I wanted to get a white one to use for art accents but I didn’t realize that the medium point markers have a felt tip and the extra fine have more of a plastic tip. I find that the felt tip kind of scratches the paper I use it on so I think for next time i’ll try the extra fine point.

Excellent for mixed media ... Coloring, writing, highlighting, you name it! Out performs all others I've tried including posterman, sharpie,and other medium points! I'm buying more!,

This paint marker works great! Good paint flow!
