This cup can be turned inside out (folding is actually the wrong word, but it's been introduced that way for years) and the space it takes up is halved as a result. A little miracle of space. Also unbreakable and light. Made from eco-friendly material. The 50% bioplastic - consisting mainly of sugar - significantly reduces the CO2 emissions during production. So - without compromising on quality - the cup becomes 'greener' and is of course recyclable.
