There is always a moment when you’re in the outside, when someone offers a drink or that you might just want to drink from a spring, share a drink with someone… well we cannot always drink from the bottle or with our hands can we? That’s when this “magic cup” is the best, it’s useless but at the same time so usefull! I hate to drink from paper cups or even worst, plastic ones, glass is “don’t take me with you” when I’m in the outside so this folding cup is the best I’ve found, it doesn’t take any space, is light, you can have a couple of them with you, they are just great!
