I checked the tags & tried to do some research online but here I am hoping for a quick answer.
I am interested in using ben wa balls for strengthening & fun purposes!
Question: Where can I purchase cheap, appropriate balls for this purpose, NOT online?
(my credit card is tied to my mom's, i don't have a huge budget & i want to make sure i get ones that are meant for this purpose, not decorative as i know some are.)
Also, I'm 21, never had a baby, one partner.. just want to double check this is safe & can only do good? my research so far says it's all good.
