Rare ONE-OFF Wtopia × Sunizumi Shoten Copper EDC Worry Stone – Silver Skull, Silver Floral & 18K Gold

Product Description

A rare ONE-OFF EDC Challenge Coin / Worry Stone created as a special collaboration between Wtopia and Sunizumi Shoten.

The piece is built around a substantial copper body, richly detailed with Wtopia’s bronze floral motif, a silver skull, and a silver floral inlay accented with 18K gold.

Copper, bronze, silver, and 18K gold come together in one compact piece, creating a layered contrast of warm and cool metallic tones.

The silver skull measures approximately 16 × 12 mm, while the silver floral detail measures approximately 12 mm. The subtle 18K gold accent adds a refined highlight without overpowering the vintage character of the piece.

Measuring approximately 31 × 19 mm and weighing an impressive 73.5 g, this compact ONE-OFF piece feels exceptionally dense and substantial in hand.

The work is further distinguished by an extensive set of individually applied markings:

• Hand-applied maker’s signature
• Sunizumi crest stamp
• Tokyo stamp
• Floral stamp
• Etsurin stamp
• Heart stamp

Together, these markings act almost like a visual record of the piece’s origin and collaboration, strengthening its one-of-a-kind collectible character.

A hand-signed certificate card is also included.

Designed as an EDC challenge coin, tactile worry stone, and collectible Japanese metalwork piece, this is a true ONE-OFF creation made in Japan.
