Collection: Synthetic Urine Kits with Warmer | Upass + Hot Sacks

Searching for a synthetic urine kit with warmer included? These Upass kits bundle Hot Sacks air-activated hand warmers with the standard 3 oz kit, so you have extra heat sources on top of the two Hot Sacks hand warmers and temperature strip that come in every Upass box. It is the most requested add-on from repeat customers, bundled at a better price than buying the pieces separately, direct from Safeguard Labs, the manufacturer.
