Glass ben wa balls are a great way to exercise your PC muscles. Just slip them in. Gravity will make them slip down, requiring you to clench your PC muscles to keep them in, ultimately making those muscles stronger. PC muscles aid in childbirth and contract during orgasm. With these ben wa balls you can do Kegel exercises, clenching and unclenching those muscles repeatedly. It gives them a better work out.

The thing that a lot of people don't know is that ben wa balls have a second function. They can be worn during intercourse or masturbation for added stimulation. Glass ben wa balls reverberate vibration well and can feel great during oral sex. They can also give added stimulation to a male partner during anal sex. For vaginal sex, I would advise being a little careful since these are glass. They can be pushed against your cervix too hard, not only causing pain, but trauma to that area.

These glass ben wa balls are not recommended for anal use because they do not have a way to pull them out. To remove vaginally, you can either pull them out with a finger or push them out. Pushing them adds to your PC workout.

These ben wa balls are made of Pyrex glass which has a safety rating of ten. Glass toys are non-porous, phthalates free, hypo-allergenic, latex free, and made of food-grade material. They are smooth and have no taste or odor. Glass can also be warmed or cooled with water if you'd like the quick temperature sensation, though they do warm to body temperature very quickly.

The glass ben wa balls are clear glass with a green and orange flower inside. If you take a close look at them you can see that they are clearly hand made. They have a small bump or rivet where the colored and clear glass meet which means they were on a glass blowing stick. This is a benefit to me personally because I know someone took time to make these instead of them being made in a mold. They are one inch in diameter, have a circumference of 3.25 inches and weigh about 0.3 lbs. They are smaller than a lot of similar products but work just as well in my opinion. Something I really love about these is that they just look like large marbles sitting in a jewelry box. If someone were to open the box and look at them, they would probably not know what they were.

These ben wa balls work just as expected. You can slip one or both in and go about your day. Because of their smoothness, they slip down easily making you have to work harder to keep them in. The cool thing about these is that you can walk around all day wearing them and no one will be the wiser.

Since these ben wa balls are glass, they're incredibly easy to take care of. Just clean them with some soap and warm water. You can boil them if you want them sterilized. Any lube is acceptable to use, though not necessary. These balls also come with a cute little storage box that hold them securely and is very discreet. It looks just like a jewelry gift box.
