・【Changes in Specifications】 We have made some specification changes to products shipped from mid-March 2026 onwards. Please note that the color of the twist portion of the cooler cap is different from the image. Change point: Changed the color of the thread portion of the “cooler cap” from black to white. There is no impact on product quality, so you can continue to use it with confidence.
【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.
