The Model D STP measures 4.5 inches (11.43 cm) from the top lip to the tip of the head and slightly smaller than the Model A STP. The Model D STP has a sturdy receptacle cup that is easy to use and requires no flow control.

Made of a Soft Powder Finish Platinum Silicone to help reduce chafing and the tacky feeling of silicone, the Model D STP has a clean, soft to the touch 'skin' texture.

Now available in cut (circumcised) and uncut (uncircumcised). 

We recommend the Slingshot Harness with this option.
