Easy to use and easy to clean the Number One works well with the Slingshot Harness and is also small enough to tuck inside briefs or carry along.

With great detail and an easy-to-use design, the Number One STP is a welcome addition to our collection. Made in the US of high-quality silicone, this has a short shaft with a generous collection end. 

The silicone means this product will last for years and is easy to keep clean (soap & water do just fine). You can also boil this for periodic sterilization if you want. The No. One is foldable and easy to tote with you anywhere.

Direction for use (from the maker):

• Make full contact with upper rim

• Aim & Go

• When finished point the No. One down and shake

Practice makes perfect!

Each product is made by hand so please note: slight variations in color may occur and different computer screens can display the colors differently, so the color may not match what you see here exactly. If you are white, you probably want the Light color. Many white folks order the medium and then are unhappy with the color.  Please note that the color not matching your skintone is not a valid reason for return. Also note that these are extremely popular and handmade and sometimes we run out of them before our system can update the stock level. We appreciate your understanding if you have to wait a few more days for yours to ship. We swear it is worth it.  

As is the case with all StPs, we cannot guarantee that this product will work for you. Most StPs take some practice using before you take it out in the real world. Please note that all sales are final.
