Materials & Care＋

Care tips to enjoy the unique texture of silver for a long time

After wearing, wipe off sebum and moisture with a soft cloth.
If it tarnishes, polish with a silver cloth to restore its shine.
Store in an airtight bag (ziplock bag) as exposure to air promotes discoloration.

About Silver
Tarnishing due to sulfidation is a natural characteristic of silver and not a defect. You can enjoy the aging process (oxidized silver) as part of its character. Avoid contact with hot springs, chlorinated pools, cosmetics, and perfumes, and prolonged exposure to water.

Size & Fit＋

This ring is free size, fitting approximately sizes 16-20. It's easy to adjust to your finger size, making it a great choice for gifting.

It's noticeable but understated. It doesn't tarnish at all, even when worn every day, and the best part is I don't have to take it off while working out.
