Double-Wall Glass Cup

A hot espresso in an ordinary glass burns your fingers, and a cold drink leaves a ring of sweat on the table. A double-wall glass fixes both.

Two layers of glass with a pocket of air between them insulate the drink, so it stays hot (or cold) longer while the outside stays comfortable to hold, and cold drinks don't sweat or drip. That air gap also gives the drink that floating look inside the glass. It's borosilicate glass, which is light and handles heat and sudden temperature changes far better than ordinary glass, and the 80 ml size is right for an espresso, a ristretto, or a small serving of tea. It's still glass, though..
