Clarus unbreakable plastic glasses, tumblers, stemware and drinkware are made exclusively from Eastman Tritan, a new generation of BPA-free plastic. Tritan provides the look of glass without the weight - and with greater toughness and durability. The Clarus collection of unbreakable plastic glassware includes plastic tumblers, mugs, and more! These plastic glasses are dishwasher safe (top rack, regular or normal cycles only, no heat-dry cycle).

Clarus plastic glasses are virtually unbreakable. They withstood extreme dish washing stress in independent testing, as well as our own extensive field tests in commercial kitchens. After more than 500 dish washing cycles researchers stopped testing, as these clear plastic glasses still showed no signs of cracking or internal haze.
