10 x 15 sensational All-Temp pack
All-Temp Therapy Pack 4" X 15"
I have been using this now for a couple of years and there is no other product that can compare. It stays colder longer and is more flexible and comfortable than any other. I am a dancer and can't live without at least two in my freezer at all times. Just came from giving my neighbor two to try for her sciatic nerve!
