8Pack Unbreakable Rocks Glasses, Old Fashioned Drinking Glasses, 100% Clear Tritan Shatterproof Tumblers, Stackable Reusable Glassware Set for Juice Beer Water, BPA Free, Dishwasher Safe MADE WITH TRITAN - Developed by Eastman Chemical, Tritan is a clear, rigid polymer 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. DURABILITY & EXCEPTIONAL VALUE - Our Rocks glasses 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! GO ANYWHERE VERSATILITY - These versatile glasses will add style and sophistication to any home barware collection, and they are also great for picnic, pool, beach and patio. Wherever your travels may take you, take them along. They will make you feel right at home. SAFETY & COMFORT - Our glasses are guaranteed BPA-free, and extensive testing has proven them to be 100% food-safe. Smoothed rims prevent lip irritation, and octagonal design on the half part of bottom, with a strong visual aesthetic. PRODUCT CARE - Our Whiskey glasses are rated to 200? 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.
