【Hi-do】Hammered Pure Copper Ring 3.5mm Width【Premium Coated Edition】

## Product Description Traditional Craft × Modern Culture Infusing the flicker of light and shadow into the deep coloration of traditional Japanese beauty, "Hi-do." This ring features a "hammered" finish, with countless facets meticulously carved stroke by stroke through the artisan's hammer-work. The uneven facets left by the path of the hammer reveal a different brilliance and shadow every time they catch the light, painting a one-of-a-kind landscape on your hand. Please enjoy this expression that, despite being metal, somehow evokes a sense of warmth. ❖ 【New Feature: Premium Coating (Tarnish Prevention)】 To ensure you can enjoy the exquisite crimson born from the artisan's fire for a long time to come, this ring comes standard with our highest-grade protective coating (glass coat). Without compromising the natural luster or texture of the Hi-do copper, this piece has evolved into a premium specification that protects against tarnish caused by sweat or oxidation, allowing you to wear it daily with peace of mind. ※ Please note that this coating does not permanently guarantee resistance to heavy impact or severe abrasion. Bumping or rubbing the ring against hard surfaces may scratch the metal or cause the coloration to peel. We appreciate your gentle care. ❖ 【Traditional Technique: The Crimson of Hi-do】 Hi-do is an ancient Japanese metal art achieved by heating pure copper to high temperatures and controlling the oxide film with a special solution to bring forth a mysterious coloration—deep reds, oranges, and occasional purples—that seems to rise from within. Used since antiquity for traditional Japanese sword fittings, it is a metal expression unique to Japan that can never be replicated by artificial colorants. ❖ 【Artisan Craftsmanship and Dedication】 Altering its expression with the slightest variation in heat, Hi-do copper is an exceptionally delicate medium. To bring out the absolute unique crimson inherent to each ring, the artisan carefully judges the exact timing of the fire-firing for every single piece. Furthermore, each facet of the hammered finish is meticulously struck and polished so that it scatters light beautifully, allowing the Hi-do colors to emerge as a highly dimensional, rich gradation. ## Product Details Material: Pure Copper (Hi-do crimson finish with a tarnish-resistant premium coating) Design: Hammered Finish Band Width: Approx. 3.5mm Size: JPN Size 1 to 30 (An additional custom crafting fee applies for sizes 20 and above due to material costs and extended production steps.

The timeless beauty of the hammered form intertwined with traditional Japanese Hi-do—we hope you thoroughly enjoy the profound depth born entirely from human hands.
