Chinese Meditation Balls

Anyone have these? Know about these? do they help?
When I was little I was so infatuated and fascinated by them and the beautiful sound they made. Now as an adult I'm into Yoga and Meditation, and I wonder if they'll be a useful tool.

 

I had them when I was younger but didnt use them correctly. I found this link for you. http://www.ehow.com/how_4866728_use-chinese-meditation-balls.html

 

Thanks. I ordered some online and I'm really looking forward to using them as meditation tools.

 

So they just arrived in the mail and I shared them with my husband.... and he told me they were Ben Wa balls, for your well.... see for yourself
