Review on 🎨 Vibrant 24-Color Acrylic Paint Pens: Ideal for Rock, Stone, Ceramic, Glass, Wood, and Pumpkin Painting. Perfect Art & Craft Supplies for Kids and Adults by Carrie Spencer

These are by far my favorite rock painting pens. You can also use them on car windows, we found out. You have 2 pages for writing strength. Just flip the top and use the other side. Be sure to shake the pins after they set as the color will settle a bit. My kids and I used them to draw rocks and hid them around our area. They dry quickly so they can be layered. The handles are also reusable. Simply remove the cap and use the tiny funnel to refill. We had to top up the white paint as we used a lot of white. I highly recommend these pens as they dry quickly, are easy to use and don't mess up! All ages can use them.
