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. 1. "3-Way Spout Tumbler": The spout has been specially designed to accommodate various everyday situations. 1) The included straw allows for a leisurely sip, making it ideal for women who wear lipstick or lip balm. 2) The small, straight spout is perfect for hot coffee lovers and is safe to use while driving. (Note: To avoid burns, do not pour hot water over 50°C into the straw!) 3) When you're feeling super thirsty, open the lid and drink directly from the cup. 2. "Safe Materials": The inner bottle of the tumbler is made of high-quality stainless steel 304, which is environmentally and body-friendly, and the lid is made of food-grade silicone and PP.
