Toyo Sasaki USURAI Tumblers - 560ml - 2-Piece

Toyo Sasaki USURAI Tumblers - 560ml - 2-Piece

The Toyo Sasaki USURAI Tumbler embodies the quiet refinement of Japanese glassmaking. Named after usurai — the thin ice that forms on water in early winter — the tumbler is blown remarkably thin, giving drinks a clean, delicate feel on the lips while remaining light in the hand. The design has been recognised with Japan's Good Design Award.

Despite its thinness, the glass is remarkably strong — the entire surface is ion-strengthened using Toyo Sasaki's HS (Hard Strong) treatment, making it far more resistant to chipping and breakage than conventional glass. The generous 560ml capacity suits iced tea, highballs, beer, and long drinks over ice. Supplied as a pair in a dedicated white gift box.
