Product Story＋

Why were a zipper and a star chosen for this ring? The zipper symbolizes "unleashing potential" by opening what is closed, while the pentagram symbolizes "protection and success," having been used as an amulet since ancient times.

This ring, combining two motifs, acts like a "key" to open new doors in your life. It gently encourages you to move forward, protected. The deepening expression of "oxidized silver" as you wear it will also become uniquely yours.

As a good luck charm, a gift, or an accent with a small wish for everyday life. This ring adds your own "meaning" to your hand.

About Silver
Tarnishing (blackening) due to sulfurization is an inherent characteristic of silver and not a defect. You can also enjoy the aged patina. Avoid contact with hot springs, chlorinated pools, cosmetics, and perfumes.

Size & Wearing＋

It is a free size (USA 7-9, adjustable) specification, allowing you to gently adjust it to fit your finger. It fits many people's fingers, making it recommended for those unsure about size or as a gift. When adjusting, avoid excessive force and widen it little by little.

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.
