All four colours arrive together, so there was no need to build a matching collection. The cups rinsed quickly at the campsite and returned to our kitchen for everyday use.

Assigning one colour to each person stopped us confusing drinks during a long lunch. Stainless steel bodies felt durable outside, and 350ml was enough for juice with ice.

Metal construction removes concern about broken glass in active outdoor spaces. Each cup feels comfortable around the rim, and the 12cm height still fits beneath our picnic shelf.

Wide 9cm bases sat confidently on our low folding table. Even when bumped, the stemless cups felt less delicate than outdoor glassware and were easy to gather afterward.

We filled these from a large insulated jug throughout the afternoon. Reusing the same colour made each cup easy to track and reduced the pile of picnic rubbish.
