This very wear-able StP is our most advanced offering to date. Carefully designed by folks who have been making (and using) StPs for years, we are proud to present to you the Flip-N-Tuck from Number One Laboratory. 

From the maker:

Made with 100% platinum silicone, the Flip N Tuck has a soft silicone outer skin and a firm silicone pee cup inside. 

When not in use the Flip N Tuck's pee cup flips up and out of the way. 

From Top of skin to the bottom of head: 7 inches or 18 cm

This is also the length of the pee cup from tip to tip: 7 inches or 18 cm

Pee cup opening: 
3 inches or 7.5 cm in length
1.5 inches or 3.5 cm in width

The Flip N Tuck comes with an elastic waistband harness. The elastic is 1 inch wide. The adjustable elastic is smooth on both sides while the inside of the fitted waistband has a softer plush finish.

This medium-large sized STP will work for most people. But may not be functional due to size being either too small or too big for the user. We are working to offer more sizes as soon as possible.

Other factors that affect the performance of any STP include what style or tightness of clothing one wears. This STP and all of our STPs work best with a classic style men's pants: generally speaking the longer the zipper the better.

Tight pants without any extra space in the crotch can make it difficult to wear and use any STP depending on your personal size and build. 

Every body is different. Our goal as a company is to continue to offer more and more sizes and styles in the future. 

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.

Like all our products, all sales are final. Not all STPs work for all people and most take practice to get right. We cannot accept returns on these for any reason.
