These gel pens glided on smoothly to an adult coloring book I used them in. Most of the colors were very rich. Occasionally a lighter color (like a yellow) came out looking streaky to me, in comparison to the other colors that glided on very smoothly. I loved the way the swirl color pens worked. They colored with various colors coming out of the pen, giving it a look that is unique to me. I wish that there could be more brownish colors because I color a lot of trees, but I'm glad there is more than one greenish color for the same reason. The colors didn't bleed through the pages. I also like how I can look through the see through pen cases to tell how much ink is left in the pens.
I'm very happy with these gel pens and know I can count on them to make the drawings I color very vibrant!
