The Chalk Talk Chalkboard Coffee Mug features a special glaze that turns its entire surface into a completely usable chalkboard. Not only can you write on it with chalk, but it erases easily and is still microwave safe.

This 11-oz "write on" mug makes for a great gift. Imagine leaving love notes for your significant other, warnings to co-workers for using your mug, or simple words of wisdom (i.e. "Never get involved in a land war in Asia.").
