First Aid Only Disposable Plastic 4 x 5" Instant Cold Pack B503-5 5 per Box

When this cold pack is squeezed, its contents – water and urea – start a reaction that lowers the temperature of the water to nearly freezing. Urea is an organic compound, sometimes called carbamide. These 4 x 5 inch instant cold packs from First Aid Only are single use only and would be a great addition to your cache of first aid supplies. Instant cold compresses temporarily relieve minor pain and swelling.
