The Knuckle 25

Let's grow!

It's time to experience that feeling that fisters crave. At 2.5 inches of diameter or 7.9 inches of circumference, it'll be challenging if you're starting out. It might take you some time to open up to it completely, but before you know it, it'll become your new best friend. The Knuckle 25 provides that feeling of fullness that a fist provides, but in a smaller package.

Do you have big ambitions? Why not get the Fist Kit which includes a Knuckle 25 along with a Knuckle 22 and 30 for an amazing price!
