My favorite feature of these ben wa balls is the pair of cute yellow flowers in the center. I also loved the discreet box they came in, which was made of black velvet with red ribbon. I thought this storage case for them was cute. The balls themselves where so elegant and pretty. Unfortunately, there are no instructions on how to do kegels or how to insert and retrieve them. They are the size of a quarter around and 0.3lb, so they're small and there's no retrieval cord.

These balls work pretty well for their intended use, which is for kegel exercizes, and for sexual stimulation as well. I just put some silicone lube on them, (any kind of lube will work) slip them in, and kegel away. They give the best feeling ever, especially when they rub against each other. They made me very wet and aroused; I couldn't take it any longer, and I had to take them out and finish with a toy because they felt so good. Also, I recommend putting them in and rocking back and forth to orgasm. These babies are lovely.

You can also use these inserted and put a vibrator in yourself to get more intense stimulation. I tried this, and it was the best feeling ever. I think every woman needs pair of these, for both vaginal health and to aid in masturbation. It can take 8-12 weeks of using kegel balls faithfully to get results.

These balls are made of Pyrex glass, so they are hard to break if dropped. They can be boiled in water to be cleaned, washed off in antibacterial soap, or even soaked in 10% bleach or rubbing alcohol. Please, by all means don't use them for anal play, as they can get stuck in the rectum.

My experience with these was that they are orgasmically amazing. They can get you wet, make you orgasm, tighten your muscles, and make sex better. Buy them and see for yourself. They're awesome!
