Toyo Sasaki USURAI Tumbler Set - 355ml - 2 Pieces

Toyo Sasaki USURAI Tumbler Set - 355ml - 2 Pieces

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 and comfortable 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 compact 355ml capacity is ideal for water, iced tea, soft drinks, beer, cocktails, and other everyday beverages. Supplied as a set of two, it is also an elegant choice for gifting.
