Double-Wall Glasses, Set of 6

Six double-wall glasses, 80ml each. The construction is two layers of glass with a sealed air gap between them, and it does two things at once: the drink stays hot far longer than it would in a single-wall glass, and the outside stays cool enough to hold without a handle.

The visual trick is the reason people buy them. Because the liquid sits in the inner wall, an espresso appears to float inside the glass with a gap of air around it. At 80ml these are espresso-sized rather than coffee mugs.

Why you'll love it

• Stays hot, holds cool — the air gap insulates both ways.
• The floating effect — the drink appears suspended in the glass.
• No handle needed — the outer wall never gets too hot.
• Six in a set — enough for a table, not a pair.

Hand wash these. Double-wall glass is thinner than it looks, and a dishwasher rack knocking against the rim is the usual way they break.
