This tin-lined guinomi sake cup from Seigado is entirely handcrafted by skilled artisans, who hammer the copper into a compact and tactile form that sits comfortably in the hand. Its small, inviting silhouette and balanced proportions give the cup a warm, approachable presence while still reflecting the quiet elegance that defines Seigado’s work.

The pattern on the surface is created by masking to leave the underlying copper exposed, then developing a dark brown tone through sulfurization. A coating is applied to the surface once the piece is finished. 

Each piece features a unique pattern, with the artisan bringing out the metal’s natural hues through careful metalwork. The result is a subtle, understated tone: a design that feels clean, composed, and intentionally restrained.

Compact yet expressive, this sake cup carries the presence of a handmade object, one that reveals the touch of the maker in every mark, and whose beauty comes from the materials just as much as from the technique behind it.
