Review on 🖍️ Castle Art Supplies 100 Gel Pens Set: A Versatile Collection for Adult Artists and Beginners - Perfect for Coloring, Drawing, Scrapbooking and Writing - Includes Swirl, Pastel, Metallic, Glitter and Neon Gels in a Convenient Case by Denise Davis

Price and variety unbeatable. Customer service is great too! When I first opened up my gel pens I immediately took out a sheet of regular carbon paper to try them out and noticed they were scratchy, then I pulled out a better piece of paper (marker paper) and it turned out to be even worse was, the thin tips of the pen dug into the paper and left lines wherever I drew. Then I tried them in a coloring book and had no problem. I've tried different books, from cheap art paper to an expensive artist coloring book. The only thing I would change is the size of the tip, otherwise it's a great product and I will definitely buy again.
