A double-walled stainless steel mug with a sealing lid, for the coffee that used to go cold on the desk by half past ten.
Construction: double-wall stainless steel.
Hot drinks: stays hot for 6+ hours.
Cold drinks: stays cold for 12+ hours.
Lid: leak-proof, to stop spills in a bag.
Contents: 1 cup and lid set.
The two walls with a gap between them are what does the work: heat has a much harder time crossing that gap, so the drink keeps its temperature and the outside of the mug stays comfortable to hold either way.
Built for the daily run rather than for show, which means it goes from the kitchen to a car, a desk, a lecture hall or a site office without being treated carefully. Coffee, tea, water or a cold drink, and the sealed lid means it can travel upright in a bag.
