Wtopia 10th Anniversary × Sunizumi Shoten ONE-OFF Silver EDC Challenge Coin / Worry Stone

Product Description

Wtopia 10th Anniversary × Sunizumi Shoten ONE-OFF Silver Collaboration

Created to commemorate Wtopia’s 10th Anniversary, this exceptional ONE-OFF EDC Challenge Coin / Worry Stone represents a special collaboration between Wtopia and Sunizumi Shoten.

Unlike the mixed-metal edition, this piece features a substantial silver body. Measuring only approximately 43 × 20 × 20mm yet weighing an impressive 95.7 g, it delivers an exceptionally dense and satisfying presence in the hand.

The design incorporates signature elements from both collaborators.

Two Wtopia bronze floral motifs with silver skull inlays are incorporated into the piece. The warm tone of bronze contrasts beautifully against the silver body, while the sculptural skull details bring Wtopia’s distinctive metalwork aesthetic to the forefront.

The Sunizumi Shoten element features a copper base with an inlaid silver emblem, introducing another layer of material contrast to the collaboration.

Silver, bronze, and copper come together within an exceptionally compact format, creating rich visual depth and a tactile character that will continue to evolve as the metals naturally develop patina over time.

Designed to be enjoyed as both an EDC challenge coin and a tactile worry stone, this is a true ONE-OFF collectible commemorating Wtopia’s 10-year milestone and its collaboration with Sunizumi Shoten.

Material & Care

Silver, bronze, and copper naturally develop oxidation, tonal variations, and patina through exposure to air and regular handling. These changes are inherent characteristics of the materials.

Gently wipe the piece with a soft, dry cloth after handling and avoid prolonged exposure to moisture, salt, acidic liquids, or harsh chemicals.

If you prefer to preserve its naturally developing patina, avoid frequent use of aggressive metal polishes or abrasives.
