Flip-N-Tuck Cut STP

Availability: In stock

This wearable StP is our most advanced model 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 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


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. 

The Flip N Tuck comes with an elastic waistband harness (1 inch wide). The adjustable elastic is smooth on both sides while the inside of the fitted waistband has a plush finish. This medium-large sized STP will work for most people. Some might find that this design is not functional for them due to size being either too small or too big.


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 skin tone 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.

This is the only stp I’ve tried that hangs with no straps around the thighs, it’s ideal for guys who like to wear boxers or free ball in hot climates. I sometimes wear this with basketball shorts, no underwear. Wish I could give it 5 stars. Unfortunately it doesn’t bend so when sitting it looks like you have a boner. Can’t even bend over to tie my shoes without looking like I’ve got something inappropriate in my pants. I wish they would fix this because no other STP out there that hangs so comfortably.
