Review on 🎨 Pigmented Perfection: Versatile Paint Pens for Rock, Wood, Metal, Plastic, Glass, Canvas, Ceramic & More! Explore limitless creativity with Odor-Free, Oil-Based, Medium-Tip Paint Markers - 28 Pack by Kelly Caballes

Used them to decorate wooden pastry knives (spreaders) and after a few months of drying the paint they're breaking like crazy. I primed some beforehand, unprimed others, but none of them stuck. Don't waste money. (I used primer, acrylic paint in the past and it worked great). Edited to add that the seller has been very accommodating after a few returns and encounters. They agreed to return the money and do more research to improve their product. Very happy with their customer service, I hope they give better instructions on surface preparation etc.
