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.

(Please check the holder size before use.) [Product Construction]: This product is made of food-grade S304 stainless steel, making it healthy and hygienic. Its airtight seal means it won't leak, even when placed on its side in a bag. While it doesn't have a handle, it's more delicate than a regular coffee cup, so a non-slip grip is best.

The lid can be opened with one hand for convenience. The small opening is designed to prevent burns.
