Review of Magcraft NSN0612 3/4-Inch by 3/4-Inch by 1/8-Inch Rare Earth Block Magnets, 6-Count

These are, as it says on the tin, very strong magnets.It's quite hard to separate them when they stick together, and surprisingly easy to hurt yourself with them, so be careful.

I don't know what I'm going to do with them, but I like them anyway.
