Ceramic - As far as keeping your coffee mug goes, ceramic outperforms glass. In addition to heat loss through evaporation, which depends on the mug’s shape and the surface area of the coffee exposed to the air, your coffee will cool off as the mug, itself, draws heat through conduction and loses it through convection. In both of these areas, ceramic loses heat at a slower rate than glass.
Microwave and dishwasher-safe - So You Can Reheat Your Customized cup and Also Put It In The Dishwasher.
AN AWESOME GIFT IDEA - A great gift idea for any music lover.
