Bests & Worsts Reviews from Amazon

I love these pens. They are great they do not bleed through if the paper is really think. I use them in Color Me Happy which is not front and back pages. They do not bleed through to the next page. I also started using them on the Creative Therapy An Anti-Stress Coloring Book and they don't bleed through to the back on the page you are working on. Just wish this maker of pens had a 72 or 96 pen set. I would so buy them if they did.
