This toy is designed to strengthen muscles while doing the Kegel exercise. One of their many uses is to intensify orgasms and pleasure during sex. Another use is to roll the balls around in one hand to strengthen muscles, and it is said to relax. I have never tried the last use so I'm not sure how well it works. I think this is a user friendly toy. Anyone can use it. It can be worn around the house while doing chores, while you are taking a walk, or while shopping, along with many other situations. I wouldn't recommend using these anally as it would be extremely unsafe.

This toy is made of Pyrex, which is a very strong glass. It can be chilled or warmed without breaking (please remember to be careful when warming and/or chilling these, as it may result is serious injury or burns). It's very smooth and firm. This toy has no taste or smell. They look and feel like large glass marbles. Anyone can use this toy.

Each ball is about 1 inch wide and seem to be perfectly round. They have a gorgeous yellow flower inside of them and the package says they are hand blown. They are very discreet and are travel friendly. Each ball is beautiful, like a work of art.

They work really well for Kegel exercise. My partner and I could tell a difference after only 2 uses. They are a bit large for the intended use, but they do work. I feel that they could be smaller.

They are very easy to care for and maintain. After and before each use, simply wash with warm water and a mild soap. Dry with a towel and place back in the container they came in.

The packaging for these balls is just as beautiful as the balls themselves. It is a black gift box, which opens like a chest. It is trimmed in a gorgeous red with a small bow tied on top. The material of this box is velvety to the touch and the inside is silky. Inside you will find two holes just large enough for the balls and spaced far enough apart that they will not clang together or break. If I had no idea what was in this box I would guess it was jewelry. As for instructions, you won't find much in this package.

I was a bit nervous about using them since they have no strings attached. In the end I found that it was harder to keep them in than get them out. So no worries there. When inserted, I couldn't hear them clang. No one knew I was wearing it.
