Cold & Hot Therapy Reusable Gel Beads Pack 7.3'' X 4.5'' (Fabric Covered)

I routine get swollen joints: knees, ankles, hips, spine, etc. This is perfect for whatever I need it for as it can be put in the freezer for cold use, or you can microwave it for a bit, and use it for heat therapy. It works for all of my sore-body needs! I also love the soft material on the back so you don't freeze your hand off in the process!!

Perfect!
