Avoiding the spiked water bottle -- not one of your best moments -- the BYOBeverage Flask makes it easy to bring a perfect single serving drink out of the house without the necessity to lug a big glass bottle or a plastic share pack. Good for alcohol and more innocent liquids of the juice and H2O varieties, this disposable flask boasts convenience across the board.

Made of a durable BPA-free material, the container can completely collapse when its not in use making it easy to pocket or put in your purse. You don't have to bother with the empty metal flask that never lets you forget its presence. The BYOBeverage Flask's capacity is about five shots, held securely in beneath a tethered screw top.
