When you were five, you wrote on the walls, floor, and any other surface your figner paint would allow.  Nowadays, you’ll have to settle for Vitamin Design’s green chalkboard coasters.  The coasters are mini chalkboards with magnets on the back that allows them to switch hit between keeping water rings off of your table and delivering messages on any metal surface.

Use them for keeping track of drinks at a party, or to tell your roommates that the dishes in the dishwater are clean.

The magnets come in a pack of four, and are 3 and a half inches in diameter.

Edit: It appears these are now sold out.
