Squeezable Glass offers all the benefits of using a glass but with the convenience and versatility of plastic. The bottle's glass-like interior provides a flexible 2-way barrier to keep beverages tasting great with every sip. And just like using glass, you'll never find leftover odors, stains, or mold when it's time to refill. All bottles are made of 100% food-grade materials and are BPA and Phthalate free. The ergonomic, textured grip provides easy, slip-free handling even when wet. And the unique cap design allows you to keep the one-way valve open without worrying about spills. With the cap off, the large-mouth opening allows plenty of room for adding ice cubes. Use the Oz. Gauge with Clear view strip for accuracy when mixing your favorite powdered drink, or place Squeezable Glass in the freezer to keep your beverage ice cold all day. Squeezable Glass can be easily rinsed and re-used or placed in the upper rack of the dishwasher. All graphics are scratch-resistant and use non-toxic inks. All of our products are made in the USA and made to last. Each bottle comes with a 17 year warranty.
