Acrylic Paint Pens Set of 12 Colors Marker Pens for Rock Painting, Ceramic, Porcelain, Glass, Stones, Pebbles, Fabric, Wood & DIY Craft Medium Tip Marker Pen (3mm)
I use these paint pens for rock painting. The thicker tip is good for coloring in larger areas. They work well and provide good color and coverage. I'd recommend them.
