The Knuckle 25

CURRENT SHIPPING ESTIMATE: 1-2 WEEKS

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 Fast Track Fist Kit which includes a Knuckle 25 along with a Knuckle 22 and 30 for an amazing price!

Not sure about firmness?

Soft is about 00-30 on the Shore Hardness Scale. It's more forgiving and will adapt more to the shape of your hole. It'll also squeeze more at entry. Soft is an excellent choice for safety and training.

Medium is about 00-50 on the Shore Hardness Scale. It won't squeeze on itself as much. While that can be an advantage, it's also harder to take, especially in bigger sizes. Those that like to play harder might prefer this option.

It's up to you!
