Works on any non-porous surface. Feels kind of similar to a magic eraser. Dry erase markers are great for glass. It's opaque and easy to erase.

This is my first foray into chalkboard arts/crafting. The silver and gold markers have a metallic shimmer to them which is neat.

The colors are vibrant & fun! All colors but the pink work great. The bright flashing lights and bright colors draw their attention.

Only suggestion i would make is to have the pen caps click on more securely. I imagine this is because darker colors have such a higher pigment concentration.

But it’s certainly easy enough to work with them, after you’ve done it a couple of times. They are also easy to clean.
