This pen makes blending my other water color pens so easy. I also found that if I use a Distress Ink stamp pad right onto my non stick craft sheet, I can then use this pen to pick up the color and use it to paint. This pen will get a lot of use from me...and the nib cleans easily by just wiping it on the non stick craft sheet a few times.
This brush is great for fine detail as well as a slightly bigger area. I am so glad a friend recommended this Water Brush Pen to me. It works great with my water color pencils. It also travels well. It doesn't seem to leak.
