Synthetic Urine is an excellent alternative to regular urine. All brands of synthetic urine are sterile and free from any drugs or contaminants to fit your uses. Many brands of synthetic urine, or fake pee come with heating pads to heat the liquid to regular body temperature. It is also common for synthetic urine kits to come with a belt to easily strap around your waist, for a comfortable and realistic experience. This urine is indistinguishable from regular urine when properly heated, and makes it some of the best synthetic urine available online, for when your local smoke shop doesn't have the right option. As always, we highly recommend the UPASS Fetish Urine product for affordability and reliability.
