The Knuckle 30

Fisting Time!

The most popular Knuckle size. It's fist size so it makes sense! It provides a beautiful pop-in feeling and filling that fisters love so much. It's 3.0 inches wide and 9.5 inches around.

If you have some experience with stretching your hole and you're missing that link to a fist, this is the one for you. If you're just starting your journey, you may want to check out The Knuckle 22, 25 or the Fist Kit which includes all three for an amazing price.

The Knuckle 30 is a perfect maintenance tool for stretching before a play session.
