The Model A is currently the largest STP from Number One Labs and measures 5.5in/14cm from the top lip to the tip of the head. The Model A is also bulkier with a studier receptacle cup that is very fool proof. The Model A is very easy to use and requires no flow control.

The Model A can fit in the Slingshot Strap-Ons comfortably.

Designed to help reduce chafing and tacky silicone feel this product has a clean, soft powder finish. The outer silicon 'skin' is soft to the touch.

Easy DIY instructions for making your own Strap-Ons out of prefabricated underwear included.

Model A:
A larger version of the Model D with the shaft measuring about an inch longer. Very sturdy & easy to use. It has a soft matte finish and a small lip so that it can fit in the Slingshot Strap-Ons comfortably. The head of the STP is painted in a realistic fashion.
