The SPORT is a compact version of the Model D. With the same shaft and head. The SPORT measures 4.25in/10.8cm from the top of the front lip to the tip of the head.
The small balls on the SPORT eliminate much of the bulk of a standard STP. The SPORT also has a shorter and less bulky receptacle cup which may take a little more practice for some.
Designed to help reduce chafing and the tacky feel of silicone, this platinum silicone product has a clean, soft powder finish.
The Sport is available in a cut or uncut option.
