When the keg starts flowing, don’t be caught off-guard. Pack a Port-A-Pint in your pocket and you’ll be ready to knock one back at a moment’s notice.
Just flick your wrist and the cup magically extends. Give it a little tug to lock it in place. Comes in it’s own storage case. Just flip, pour and enjoy! Measures 3.5″ diameter when closed.
Go from pocket to pint in seconds with this folding pint glass at Amazon via Gizmodo.
Pardon us please, while we pay for beer...
