Our innovative, thick-walled glasses made with Eastman Tritan™ Copolyester are as tough as nails. Consequently, Drinique drinkware is the closest thing to indestructible that you will find anywhere. We guarantee our glasses won’t shatter, break or crack. This isn’t a dare or anything, but if they somehow break, Drinique’s got your back. We’re so confident in our product that we promise to replace any glass that breaks, shatters, or crack (under normal use) for life! If you have a problem, we want to hear about it.
