No picnic is complete without a selection of refreshing drinks to choose from. But using real glass cups outdoors is sure to result in a few breakages, and flimsy plastic alternatives are hardly the height of picnic chic. With these tumblers on hand, however, you’ll be sipping juice, fizzy pop or even a cheeky glass of wine before you know it, without worrying about broken glass or having to drink from disposable ‘kiddie’ cups.
