This set is shaped like mangos (!!) and is great for the person looking to up their kegel game. It comes in three cute colors yellow is 1.5 oz, red is 2 oz, and orange is 2.75 oz so you can increase your weight over time.
The creators of this recommend users insert, and squeeze for 10 seconds. They recommend doing no more than 10 reps at a time, so keep that in mind before you go H.A.M. with your new mango balls.
