Precious metals may undergo a chemical reaction when immersed in hot springs containing sulfur, which may cause discoloration. Please remove your jewelry when bathing.

Please refrain from wearing jewelry during strenuous exercise, while sleeping, or when caring for small children, as this may cause injury or damage to the jewelry.

Also, if you leave it for a long period of time, it may turn black. After use, please put it in a zip-top bag to avoid exposing it to air as much as possible.

Depending on your constitution, you may experience itching or a rash. If you notice any abnormalities on your skin, discontinue use and consult a specialist.
