Cool ID Tumbler
Available at: Thegrommet.com
Say cheers to ceramic tumblers that keep beverages perfectly chilled. Submerge the tumblers in cool water to activate their natural cooling properties. This ceramic absorbs the water quickly, leaving the surface dry, so thereâ€™s no condensation, inside or out. Your drinks stay cool for hours. The matte surface is sophisticated and also acts as a chalkboard if you want to write on it.
