These tumblers have been run over by a car, smacked with a baseball bat, and well tested with heavy restaurant use - all without breaking. So, it's safe to say your daily use onboard, poolside, or in the beach house dishwasher is not a problem.  

These crystal clear plastic tumblers are BPA-free. They keep drinks cold up to three times longer than other plastics and glass!  

Available in three styles. Sold in sets of four.
