Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. Size: W125 x D89 x H150 (including handle) Diameter 89mm Structure: A stainless steel mug with a three-layer vacuum cooling structure (ice pack layer + double vacuum insulation layer) that can quickly cool drinks to below freezing. Cooling: Simply pour your drink into the frozen body and the temperature of the drink will drop rapidly. Even room temperature drinks can be made ice cold by using the frozen body! How to use: If you pour a drink straight out of the refrigerator into the freezer-chilled unit, it will cool to below freezing in as little as 60 seconds and keep it that cold. Caution: The cooling effect is so strong that if you leave a drink in it, it will turn into sorbet.
