WHAT IS TRITAN? - Developed by Eastman Chemical, Tritan is a clear, rigid polymer/plastic that outperforms all other acrylics and plastics in food-based applications. Tritan looks and acts like fine glass and emulates its best features, but unlike glass, it is unbreakable.;STYLE, DURABILITY & VALUE - Ambassador Rocks glasses are seamless, and they can be dropped from a bar or table onto a tile, concrete or hardwood floor without chipping, cracking or breaking. They will not require replacement for many years, and that means exceptional customer value!;DUAL-PURPOSE VERSATILITY - These versatile glasses will add style and sophistication to any home barware collection, and they also make superb, all-season juice glasses; great for pool, beach, patio, and camper. When you travel, take them along.;SAFETY & COMFORT - Our glasses are guaranteed BPA-free, and exhaustive testing by Eastman has proven them to be 100% food-safe. Smoothed rims prevent lip irritation, and recessed, ergonomic shams create great hand feel and a comfortable grip.;PRODUCT CARE - Our Ambassador glasses are rated to 210?Fahrenheit. They are dishwasher-safe, and a simple wipe with a soft cloth will enhance their brilliance and clarity; REMEMBER - Never use scouring pads on any type of plastics.
