Ben wa balls are smaller than that unless you just get industrial size lol these are Chinese meditation balls for stress relief and the help center yourself
These are NOT stress balls. They're Ben Wa balls, and they're used for strengthening pelvic muscles. Meaning...is that really something you want to purchase used?
They are as big as a golf ball. the box is about 3 inches wide and about 2 inches tall. And yes these are considered meditation balls. I have no clue what you're talking about with straightening you're pelvic. No one has touched these things since my dad got them over seas and he was told from who he bought them from that they were Chinese stress balls.
lol @betty.. these things are WAAY too big for that >_<; man, I used to have these waaay back when, cool item! love how they 'chime' definitely watching, great listing!
