Review on 🖊️ Dyvicl White Ink Pens - 12-Piece Fine Point Tip Gel Pens for Black Paper Drawing, Illustration, Rocks Painting | Perfect Sketching Pens for Artists and Beginner Painters by Megan Marshall

These pens don't work at all. The packaging on the back warns that they may not work and how to fix them. Your fix doesn't work. I work with graphite and charcoal. To use these pens, I have to press hard enough to make deep dents in the paper. It's like they're completely dry. They do not do anything. I found an email address on the back of a pen box. I emailed them very politely and asked if there was anything they could do. The email address was in Hotmail and was not a valid address. I wish there was a way to tell Revane.
