When I first saw this, I though to myself, “Wow! What a great idea!” Then my pesky brain got involved.
Basically, this is a drinking straw holder with a tumbler underneath, and really has very little practical value, apart from the the extreme novelty and jealous stares you will get until other people’s brains kick in. This guy, however, REALLY seems to be drinking from this cup. He must be reading this blog :)
For 7 bucks, can you really go wrong? Get the cell phone holder party cup here.
