This unique set of drinking glasses is made out of superior Tritan copolyester that makes each glass impact and shatter-resistant. This premium material feels and looks like glass but it’s far more durable than any other plain glass or plastic drinkware set out there. Feel free to get as clumsy as you want with our glasses, and enjoy your favorite beverages at home, patio or any pool, boating, camping, picnic, hiking, or outdoor excursion that you wish!
