Here’s the problem – when drinking water outside the home or office, you need to carry a bottle, drink from a faucet or ask for a disposable cup. The first one is inconvenient, the second unhygienic and the third one harmful to the environment. The solution is this rather ingenious leaf-shaped silicone pocket cup. You carry it around in your pocket, wash it, have a drink and then stash it away again. It comes in a set of three, and makes you look very earth-friendly.
