Q: what kind of grinder is this?
A: It is a coffee bean grinder. You can get them for about $10 at Target, but I suggest you upgrade to something a little more sturdy and spend about $30.

This video is a must watch. It shows you exactly how to grind the colors together and then shake them together with the base. It also gives you a neat trick for making less of a mess!!! A must watch!

you will need to get a better coffee grinder. I got one from WalMart for 15 and it has already gone out. I upgraded and quick.
