Drink your morning coffee out of a mug that really fits your personality! Perfect for gifts. These heavy duty mugs are ceramic and hold 16 oz. NEW ORGANIC INKS! The mugs are now decorated with organic polymer inks that are compliant with CALIF PROP 65. Dishwasher and microwave safe, but it's always best to handwash decorated ceramics. All designs listed are available now but a word to the wise...a handful of personalities will be retiring soon, so quantities are limited.
