The hairbrush flask is indeed a hairbrush that is a flask. To use it just unscrew the bottom of the brush, fill it up with your favorite liquor, beer, juice, coffee, or animal urine, screw the cap back on, and stash it in your purse. Then when you are at your next sporting event, concert, or animal hunt, take the brush out as if you are about to brush your long beautiful hair, but instead take a sip and continue to get extremely fall-down drunk. The hair brush flask is a fully functional brush that holds up to 6 oz. of liquid, has a mirror on the back of the brush for spotting security guards, and includes a small flask for easy filling.
