Care Instructions
■ 18K Gold Products
No special care is required. However, please be aware that prolonged exposure to sweat, hot springs, seawater, or pool water without proper cleaning may cause discoloration or damage. When storing for a long period, we recommend gently washing with soap, wiping with a soft cloth, and then storing.
■ Silver (silver925・950) Products
May gradually oxidize and tarnish when exposed to air and water. Also, may discolor or corrode when reacting with chemicals or hot spring components.
■ Brass Products
A material prone to oxidation and reacting to sweat. While shiny when polished, extended use will develop the unique dull luster characteristic of brass.
■ For items with a polished finish that show dullness or discoloration, they can be cleaned with a polishing cloth containing metal polish. Purchase a polishing cloth here.
■ For items with a matte finish, please refrain from using polishing cloths containing abrasives. This may damage the surface texture. If concerned about dirt, wipe with a soft cloth.
Handling Precautions
■ Discontinue use if skin irritation occurs.
■ Bracelets and earrings may have shapes that can easily catch on hair or clothing. Please be careful when wearing them.
■ Strong impacts may cause damage.
