You know what they say: Nothing takes the callouses off like fastening plastic bags filled with urine around your feet.
The Foot Pee! Pack, essentially two ziplock bags intended for your feet, supports an age-old philosophy that one's pee can have benefits to their skin. Now I'm no expert, but I've been accidentally urinating on stuff for years now, and I can't say that my crotch, toes, knees, backyard bushes or bathroom walls look any younger because of it.
