This design is laser etched directly into the tumbler. The artwork will not peel or scratch off. We recommend hand washing, but this product is dishwasher safe. 40 oz. Polar Camel Tumblers feature a double-walled vacuum insulation with a clear snap lid, straw and carry handle. The tumbler has a narrower bottom to fit most standard cup holders. It is 2X heat & cold resistant compared to a normal tumbler.
