I use prismacolor colored pencils in all my Bibles. **Q: Where can I buy refills for this pen?** A: You should be able to purchase refills here on Amazon **Q: Can you right on a rock with these?** A: I have not tried to do so, and I really doubt that fine of tip would work very well. I guess I would experiment to see if you could. They do make pens especially for writing and painting on rock. I would recommend that type of pen, but try these to see. **Q: Has anyone colored with these?** A: My uni ball Signo RT1 collection of color gel pens are of 0.28 mm fineness. They are very very fine point. At such fine point, I think you can only write with it. I think it will be hard to color anything with it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***E on October 7, 2025* A lefty’s dream come true!
