The average American will spend up to 1 hour per day commuting in their car. These stunning condensation absorbing, round ceramic coasters will help capitalize on this opportunity. They're sized to perfectly fit into most cars, van, trucks & SUV cup holders, & are mildew-proof & is easy to clean with just a quick rinse with water. They look great with either a one-color pad or a full-color digital imprint, although the nature of the porous material will mute some color brightness & vibrancy. Complies with Prop 65.
