Doshisha Tumbler 260ml, Freezing Tumbler That Cools To Below Freezing Point, ON℃ZONE (Ondozone) Vacuum Insulated, Navy, OZFT260SNV

This tumbler can cool even unchilled drinks to below freezing point. Its 3-layer construction (cold-storage layer (inner) + 3-layer vacuum double layer (outer)) ensures long-lasting ice retention. Simply place it in the freezer and pour in your drink; wait 30 seconds and your beverage will be below freezing. Using 4°C water (water at the temperature of a refrigerator), it will reach below freezing in 30 seconds. Please note that leaving the drink in for too long will cause it to turn into a slushy. You can't really add ice to beer, can you? This freezing tumbler is perfect for drinks that can't be chilled with ice (beer, cafe latte, juice, etc.). Of course, it's also ideal for highballs and chuhai.

Pour your drink into this tumbler frozen in the freezer and it will reach below freezing point in no time.

Vacuum insulation keeps drinks cold.
