Chalkboard’s aren’t just for the classroom anymore. With the bottom of these wine glasses dipped in chalkboard paint, remembering which glass is yours will be a breeze, no “wine charms” required. Just customize the message on the base of your glass with anything you’d like. Tip: more cursing = better odds that nobody will touch your glass.

Chalkboard China stocks a variety of chalkboard glasses among other things – starting at 20$. Or, if you’re low on funds, just get some paint and make your own – available wherever paint is sold.
