【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.

・Never heat in a microwave or place over a direct flame. ・Pure copper products without a clear lacquer coating on the surface will discolor. ・Verdigris may also develop if used in a humid environment. ・Verdigris is harmless, so you can continue using it as is. If it bothers you, it can be easily removed by rubbing with a cloth mixed with vinegar and salt. ・The discoloration described above is not rust, but a coating produced by the copper itself to protect it from oxidation. While the color can be restored by polishing with a copper-specific cleaner, you can also enjoy the changing color of pure copperware as it ages. ・Please consider this aging as part of the unique charm of pure copper, and we hope you will enjoy using it for many years to come.
