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. Ceramic Tumbler: Made from high-purity ceramic and fired at high temperatures, the smooth, non-porous surface resists odors and bacteria, preserving the original flavor of your beverage. The ceramic surface is highly stain-resistant and can be cleaned directly with a soft cloth or sponge. Stubborn tea stains can be easily removed with baking soda. Double Vacuum Insulation: Insulation performance: A vacuum barrier between the inner tank and the outer stainless steel layer, equipped with a sealed ceramic cover, maintains high temperatures (above 70°C) or low temperatures (below 10°C) within 6 to 12 hours Switch between direct drinking and straw use: Even though it has a large capacity, it comes with a straw so you can drink quickly at any time. The straw lid prevents leaks even when the bottle is knocked over. Easy to carry: The ceramic liner has a low density and is lightweight overall, making it easy to hold in your hand or carry in your bag for long periods of time. It's easy to carry, making it convenient and practical for commuting, traveling, outdoor activities, and more. Capacity: 500ml Simple design: The cup features a slightly curved, cylindrical base to avoid sharp edges and corners, allowing it to fit comfortably in the palm of your hand. It's suitable for offices, libraries, and outdoor settings, blending seamlessly into a variety of environments. Tumbler
