It is said that Kegel Balls work best in strengthening the bladder and tightening the walls of the vagina. This can be achieved by inserting and holding them in place for about 15 minutes a day. Includes two Kegel balls, each about an 3/4 inch in diameter.
 
How to Use 
Before inserting the balls into the vagina use the restroom and empty your bladder.

Lay down if you haven’t done this before, then insert the ball (or balls)
Hold the balls inside you by tensing your leg muscles together and your PC muscles, start out with 15 minutes then try to go longer.
Remove the balls by standing up, coughing, or if you’re still having trouble you can sit and bear down as if you were having a bowel movement.
