Pentel Sparkle and Krazy Pop, Metallic Gel Ink Pen, (1.0mm), Bold Line, Assorted Ink Colors, 12-Pk

These are excellent gel pens, the best I've tried. Great flow and beautiful colors. The Krazy Pop pens are fun because I didn't know what to expect. The ink seen through the clear pen body (I don't know what it's called) is so pretty. There is a very slight scratchiness now and then when they write, but it's minor and not a problem. Great on white or black paper.

Awesome shimmer and sparkle! Write very smoothly. Excellent for detailing calligraphy or writing faux

Absolutely love these! I didn't know what to expect but I can see why people rave about them. The color pay off is amazing and the sparkle is out of this world!
