Handmade in the USA, Number One Laboratory specializes in realistic 100% soft platinum-cured silicone STP packers. These STPs are easy to use and comfortable to wear.
Model A is the sturdiest STP from Number One Laboratory.
Because it's a bit bigger with a larger receptacle cup, the Model A is extremely user-friendly. With its generous space to pee into, no flow-control is needed.
This STP fits best in pants with a longer zipper, and is compatible with the Slingshot Harness. It also includes instructions on how to easily construct a harness from a store-bought pair of underwear.
The Model A's outer silicone 'skin' has a clean, matte texture that is soft to the touch. And its powder-soft finish is designed to help reduce chafing and remove any tacky silicone feel.
The Model A is available in an uncut, or cut option.
Available in three colours: light, medium, dark.
Material: 100% silicone
Size: 14cm (from top lip to tip of the head)
