Cinder blocks may have fallen out of favor with everyone but the mob due to advances in building materials, but they’re still iconic. These Cinder Block Magnets (made of real cement!) can be used to hang the shopping list, to-do list, Christmas cards, pictures and anything else fridge worthy on a magnetic surface. They’re absolutely no good at disappearing things, but that’s probably not a purchase you want tracked on the Internet anyway. As long as you want magnets, this four pack of cinder blocks will do the trick.
