Review on DPG No-Wax, No-Clay, No-Glue Diamond Painting Pens - 2 Pcs Tools for DIY 5D Painting with Diamonds - Self-Stick Drill Pen & Specialty Design Accessories Kit by Dawn Fischer

I rated this pen on the first day of use. At first I thought it works well, but after further use it has its limits. The pen is like chalk, so the tip was too wide in many places in the drawing. This made it difficult to place the diamond without snagging on the surrounding diamonds. Maybe using a crayon sharpener to sharpen the tip would help? I am not sure. Also, the end will become "crumbly" with prolonged use, leading to delamination. This happens to me with regular wax, so it's ok because it's easy to remove. I think this pen has a purpose, but probably more so at the beginning of projects where there is more space around the diamonds.
