I haven’t used the gel pens as of yet, however I did use some of them to see how they would look on paper and they are very nice, the colors are true to wants in the barrel.

I love the extensive array of colors and variety of mediums like the glitter, metallic, and pastels and the depth of color they add to the picture. Looking forward to using them on other projects. 😊👏

Very satisfied with the products from Castle Arts. We have the gel pens, which my husband prefers & I use the colored pencil sets. Love them!
