A Royal College of Art project, Half Pint Mug has two walls so the outside never gets scaldingly hot. If a hot drink is poured into the mug, the air between the walls warms up and serves to keep the drink warmer for marginally longer.
The profile of the mug is borrowed from the standard British pint glass, known as 'nonic'. As well as being comfortable the shape ensures the rims of the mugs never clash if more than one is picked up together.
The mug is in production in Stoke-On-Trent, England, is distributed through the company Innermost.
