This 70 g set is geared more towards beginners where 1 of the 2 balls are interchanged. As you feel your muscles strengthen its easy to change to the higher weighted balls. Using the I is a fantastic goal building kegel workout.  Stella I is perfectly manageable and a complete pleasure to use. Each smooth, silky ball slides out of the snug girdle for easy cleaning- when replacing, be sure to position the plastic Key logo upward.
