Product Story＋

An intentionally imperfect, irregular form. The shadows created by its distortions and undulations bring a retro, artistic expression to your hand.

For those who find uniform designs unsatisfying, this piece makes a subtle statement of individuality the moment it adorns your finger. It's also perfect for adding an accent to a simple outfit.

Made from S925 with 92.5% purity. The "smoked silver" patina that develops through sulfurization will grow into a unique texture that is yours alone over time.

Material & Care＋

Care tips to enjoy the unique texture of silver for longer

Wipe off sebum and moisture with a soft cloth after wear
If tarnishing occurs, use a silver polishing cloth to restore shine
Store in an airtight bag (ziplock bag) to prevent discoloration from air exposure

About Silver
Tarnishing caused by sulfurization is a natural characteristic of silver and not a defect. You can enjoy the aging process (patina/smoked silver) as part of its charm. Avoid contact with hot springs, chlorinated pools, cosmetics, and perfumes.

Size & Wearing＋

This item is adjustable within USA sizes 7-9 (approximately Japanese sizes 17-19). You can gently adjust the ring to fit your finger, making it a reassuring choice for those unsure about sizing. Please adjust slowly within the appropriate range.

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.

I have a metal allergy, but since this is surgical stainless steel, there's no rash. I even wear it in the ocean and there's no discoloration, it's the best.
