Don't get caught without The Whizz Kit! This Synthetic Urine Device is prefect for when you have to go and you weren't expecting to. It comes pre-filled ready to go straight out of the box. It only needs to be worn for about an hour before it's ready and at a life-like realistic temperature. The Synthetic Urine is medical grade and is chemically similar to human urine, just missing your own personal DNA. Comes with a syringe so refilling and using over and over is a breeze.
