Our popular Climate Lock™ vacuum insulated food canisters just got even better. Now with TK Closure™ thermal technology, Canisters keep food hot or chilled even longer. We’ve replaced the traditional external thread closure system with a revolutionary internal thread closure that forms an all-stainless insulated barrier to trap heat or cold. Food never comes into contact with plastic and stays fresh for hours. But that’s not all. Our new, wide-mouth design makes filling and eating from Canisters easier than ever. Screw off the lid and boom, you’ve got a bowl that is both functional and stylish. When you’re done, the lid locks into place with just a quick quarter turn.
