Black+Blum built this 340 ml travel cup around a single promise: it should be handed over a counter to a barista and taken away again without a second thought. The stainless steel body keeps drinks hot for five hours, and the top is fully leakproof and lockable, so it can travel in a bag next to a laptop.

Drinking from it is deliberately unfussy. The lid opens for a wide sip rather than through a narrow spout, and the whole top disassembles for cleaning, which is where most reusable cups quietly fail after a few months. Construction is stainless steel with PP components, sized at 7.2 centimetres across and 16.5 centimetres tall to fit standard cup holders. It is handwash only, the trade-off for that seal quality, and it arrives in a gift box in grey, orange, turquoise or green.

Reusable cups are the standard tool of any single-use reduction programme, and this one is durable enough that recipients keep using it long after the campaign ends. Office rollouts where disposable cups are being withdrawn, sustainability weeks, coffee roasters selling branded merchandise, coworking spaces and conference welcome desks all fit. Given in a spread of colours, it also works as a team gift where people need to tell their cups apart.
