Review on 🖋️ Optimized Speedball Sketching Pen Set - 2 Penholders with 6 Pen Tips by Nancy Bryant

Took out the small nib holder and couldn't insert the small round nibs. I had to redrill the hole to fit the tips. The little pen wrote very well, as expected. Became much wider than the line on display on the way down. It was difficult to insert a pen into the large pen holder. By placing the largest tip in the holder I was able to get a nice thin line and good highlights as I moved down. It is still very difficult to change tips.
