The added weight is a good benefit I really enjoy using these balls. Couldn't fit any better does the job well.
Definitely keeps the muscles strong
These Ben Wa Balls would be ideal for somebody who hasn't used them before. Nicely sized - not too big, not too small. These balls do not have the inner rolling ball inside, so there is no subtle vibration when wearing them. The material is of soft silicon, which means it's easy to clean and you can wear them pretty much anywhere.
