〔Care Instructions〕
■ 18K Gold Products
No special care is required. However, please note that leaving the product in contact with perspiration, hot spring water, seawater, pool water, or similar substances for an extended period may cause discoloration or damage. When removing it for long-term storage, we recommend gently washing it with soap, wiping it with a soft cloth, and then storing it.
■ Silver (silver925・950) Products
Contact with air or water may gradually cause oxidation and darkening. The material may also discolor or corrode when it reacts with chemicals or components in hot springs.
■ Brass Products
This material oxidizes easily and reacts readily with perspiration. It shines brightly when freshly polished, but with extensive use, it develops the characteristic muted luster of brass.
■ If glossy-finish products become dull or discolored, they can be cleaned with a cloth containing metal polish. To purchase a cloth, click here
■ Do not use polishing cloths containing abrasives on matte-finish products. They may damage the surface texture. If you are concerned about dirt, wipe the product with a soft cloth.
〔Care Instructions〕
