Not sure about firmness?

We recommend soft for this item because of it's size.

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. Those that like to play harder might prefer this option.
