These great little heat pads have the same great heat therapy and aromatherapy benefits as our larger wraps. Heat Pads can be placed anywhere on the body that needs heat therapy. The fold-over flap keeps the removable insert inside. For cold therapy, place in a zip lock bag and put in your freezer. Heat pad can go from freezer to microwave. Flax seed does not clump together so the heat pad is always flexible where ice bags form one solid mass of ice after thawing and refreezing. Size: 12" x 10"
