DOSHISHA Freezing Tumbler OZFT-260 Stainless steel, 260ml Use after freezing in the freezer Stored after using 2-3 times. No noticeable scratches or stains. [Product Description] Size: Approx. φ72 x 160mm Structure: A stainless steel tumbler with a vacuum cooling 3-layer structure (refrigerant layer + vacuum double insulation layer) that can rapidly cool drinks to below freezing. Cooling: Simply pour a drink into the body that has been frozen in the freezer, and the drink's temperature will plummet. Even room-temperature drinks will become ice-cold when using the freezer-chilled body! How to use: When pouring a drink straight from the refrigerator into the body chilled in the freezer, it cools to below freezing in as little as 30 seconds, and maintains that coldness. Caution: The cooling effect is so strong that drinks will turn into a sorbet if left inside. This is a sale of the body only, without a box. Ships via Yu-Packet Plus.
