I really like using this pen. The ink/paint comes out nice and smooth, and the line is nice and thin (not too thick and not clumpy). You have to re-draw the line a few times for the writing to be completely opaque, but it's worth it.
Love my pen! Great for doodles. Writes smoothly and very opaque! I can't recommend this product highly enough and often get additional pens to share with friends.
I haven't use the pen but I know it's going to work! It's nice to know one can depend upon a thing that works! Yea!
