...A fusion of tradition and innovation, this premium tumbler “Proof-of-Craft Tumbler by Metaplanet x Nousaku” is meticulously crafted in Toyama by Nousaku, a legendary foundry in the city of Takaoka with over 100 years of metalworking heritage.
Toyama is renowned as Japan’s heart of traditional casting, and Nousaku brings that legacy into the modern age with this 100% pure tin tumbler—celebrated not only for its antibacterial properties, but also for enhancing the flavor and mouthfeel of cold beverages like beer and sparkling water.
Etched with Metaplanet's iconic “M” logo, this piece is more than just drinkware—it’s a symbol of craftsmanship, resilience, and a shared belief in long-term vision. Whether for thoughtful gifting or your daily ritual, it’s a vessel that connects Japan’s artisanal past with Bitcoin’s decentralized future.
*Each piece is handcrafted by Nousaku artisans in Toyama Prefecture.
