Drink in the Box is the world's only reusable juice box! It is patented, BPA and Phthalate free, won't squirt or leak, and helps to hydrate your kids without all the sugar and risk of mold, or impact to the environment of a disposable juice box. Drink in the Box is made of a high-end US-made material, called TRITANTM, which is the highest quality, and safest material you can use. TRITANTM is BPA and Phthalate free. It won't warp or crack in the dishwasher. And unlike stainless steel, TRITANTM won't dent or ding. It will withstand more than 1500 dishwasher cycles (3-5 years) and is clear like glass (but won't break like it).
