Folding Cup concept design

How many times have you gone to a party and mistook your drink for somebody else’s? The Folding Cup concept design avoids such embarassing moments (which is why I tend to gulp down my beer as soon as possible lest I share somebody else’s saliva by accident) as it features a range of letters, numbers and card symbols which you can set accordingly so that you won’t mix it up with another cup. The only downside to this would be alcohol fueled parties – how many of us will be sober enough after a few rounds to know just which symbol we have set in the first place? I suppose writing your name on the cup would make the whole process much easier.
