Hint........it feels good when I use it..............and I bought it at Dollar General!
(and for all you pervs, NO, it's NOTHING like that!)
I KNOW, I KNOW!! And I want one. I have only seen this one other time, and wish I'd bought it then. That was about 4 years ago!
I really don't know what you call it, but you hook it over your shoulder and pull it forward to put pressure on those nasty muscle spasms you get next to your shoulder blade where you can't reach! It's a self-massager.
