I bought my first bong in Berkeley in the 60's from a wonderful store called The Body Shop (before The Body Shop of England bought their name). I think it was about 10 years ago when I thought the rubber ball had petrified and I thought I'd never find one again. Spring. Amazon has them. They are sold in pairs but as I am working on my own trigger points I am only using one for now. When my neck, shoulders, and upper back get cold from my "myofacial disorder," these things are great for sore muscles and trigger points into submission. I hope never to be without one or two again! It's trite, but it really is "it hurts so much."
