The Ben Wa Balls by Nasstoys are another set of your run of the mill vaginal exercisers. They work quite well but there is one major drawback to this particular set: they get sticky for some reason after you clean them.

The purpose of vaginal balls is to aid in fitness of the PC muscles. They are used by inserting them (like a tampon) and wearing them throughout the day. There are small weighted balls inside of them that move and cause subtle vibrations here and there (nice little surprise to keep you in a good mood).

Now these are your average kegel equipment size- weighing in at less than a pound and measuring around 1 1/2" in diameter. They are a bit larger than a ping pong ball and are attached by a nylon cord that doubles as a retrieval cord.

I could actually feel these balls inside of me- when I turned the corner while driving, when I sat down or stood up, or moved by balance slightly. Most sets that I have can be felt with some work, as in bouncing up and down or hopping up the stairs, but these actually move around on their own.

Now for the strange part - the stickiness. After cleaning these and leaving them to air dry they became sticky. The first time I noticed this I had used regular soap and warm water. Next time I tried to rinse them off on their own and use a toy wipe, they still ended up sticky. This led me to wonder what kind of material is really coated on them - I know that more porous materials such as Cyberskin and Futurotic require dusting with corn starch to prevent them from getting sticky, and I have never had silicone get sticky on me before.

After doing a little bit of research I have found that the closest product to these on Nasstoys' website is the Vibrating Ben Wa Balls, which are advertised as being made out of realskin(which is completely porous and needs to be taken care of carefully).

These balls are labeled as being made of plastic on the material page, but after doing some research I think it is actually this Realskin or something very similar.

Realskin is one of the materials that requires corn starch after cleaning to prevent it from being sticky - do not use products with talc, as it has been linked to cervical cancer. Honestly, I recommend using these sparingly or for a short time as porous materials can absorb all sorts of bacterias and dyes, and leaving something like this in all day and using them often can result in infections.

To store these leave them in a cool dark place on their own, and keep them away from other things to prevent pick up of bacterias and dyes. Wash before and after each use.
