Model E STP - 3"

by Number One Laboratories


This is the absolutely smallest STP on the market. Designed specifically for FTM trans youth (ages 8 - 13) this STP is made from 100% body safe platinum silicone with a powder soft finish. The outer silicone 'skin' has a clean, soft matte texture which is designed to help reduce chafing and remove tacky silicone feel. 


Number One Laboratory* STPs are made from Platinum Silicone with a soft powder finish. Every model sold is completely handmade using the best materials available and thoroughly checked for quality and durability. 

- Shaft Length: 3"  
- Width: 1.25" - 3.2 cm. 
- Height (from below balls to top of shaft): 3"

Platinum silicone may be cleaned using any one of the following methods.
- Hot water and soap
- Diluted bleach
- Overnight denture cleaning tablets
- Boil for 3-5 minutes


Note for first-time users, we strongly recommend that you practice in the shower before attempting to use in public. Even if you have had success with other STPs in the past, every STP is different and requires some getting used to. 

*This company used to be called Form Function
