Ideal for casual outdoor entertaining or summertime outings, these truly unbreakable pint glasses are made from 100% BPA-free, food grade silicone. Silicone – which is derived from sand – is considered a sustainable material due to its non-toxic composition, extremely long life, and ability to be recycled. Serve beer (of course), iced tea, water, and other beverages without worry – just stack them up, throw them in a bag, and go. The translucent "Icicle" color is a frosty, ultra pale blue, that lets you enjoy the color of the beverage you are drinking. Dishwasher, microwave, and freezer safe. 16 oz. capacity.
