This is a set of balls designed to work your kegel muscles. You place them inside of yourself and the effort to keep them inside your body is what works the muscles. It's a lot like holding in your pee. The toy is really only intended for use that way, though some users say when the balls clink together inside of the vagina the vibrations from it can be stimulating and arousing. The toy is intended to be used when you are doing housework or otherwise moving about the house, not to be used while sleeping, lying down, sitting down, or making love.

The material is a beautiful heavy glass, like large marbles with purple butterflies trapped inside of them. The glass balls retain temperature well so when first inserted they feel so cold I get shivers. Because they are so smooth they have no seams and there is no difficulty during insertion. Of course they are very firm and once wet, they are slippery making removal very difficult.

The balls are discreet, seeming to be just two marbles in a pretty case. They are well sized and most users should have no problem inserting them. The big problem is in removable. The idea behind the design is that the heavy glass will make it hard for the muscles to hold the balls in while the wearer is doing the average standing things. However in my case they traveled up instead of down while I washed dishes and walked the dog. They got stuck and because they are smooth glass they were very difficult to get out!

The fact that I didn't feel my muscles working at all made this toy an instant flop. There was nothing to even keep them from putting pressure on my muscles. As soon as they went in they traveled up and up so that I could barely feel them at all. I reached a finger as deep inside me as I could and still could not find them. My husband laid me back so he could see, shined a light and reached as far as his long fingers could and could only barely touch them. Not only did they not work at all they were stuck inside of my body for two hours while we panicked and frantically tried any way we could to remove them.

It took a long time, struggling, tears, and we even considered an embarrassing and expensive ER trip. But oh so slowly he managed to coax first one, and then the other near my entrance. Still they were so slippery from my juices he couldn't get them to come out. They wanted to stay in there! He had to reach his finger inside me, curl it around each ball and scoop it out of me, stretching my entrance more than it ever had before as his finger and the entire diameter of the unforgiving hard glass ball had to both squeeze through. I sat through the pain twice and vowed never to let balls enter me again without a retrieval cord. It was a terrifying experience.

Cleaning them afterward was very easy and simple since they are made of glass. Simply wash them with soap and water and hope you don't get them too slippery or they will squeeze right out of your hand and go down the drain. Storage is simple and easy. They come in a cute heart shaped container in which is a plastic form that holds the balls and a small square of satin to go between the plastic and glass. It makes a cute storage design and is still pretty small.

Because the toy comes in such a stylish little purple tin, it makes a great gift idea if you want your friend to hate you for giving them such a horrible product which can be scary and dangerous if it doesn't behave properly.
