These Life and Limb Gel packs measure just 4" x 6" including a 1/2" seam and weigh only 3 ounces each, making them the perfect tiny size for schools, dental pain, or minor injuries. Our products are suitable for both hot and cold therapy, and are great keeping food cold in a cooler. Look at the line of Life and Limb Gel wraps that add convenience for using our hot and cold therapy gels. Life and Limb Gel is the number one choice when it comes to hot and cold therapy: created and tested by medical professionals, our USA hand constructed products are durable, safe, affordable, and backed by a money back guarantee! Hot therapy can help soothe and relax sore muscles, can reduce arthritic joint pain, and can stimulate blood flow to accelerate the healing process. Cold therapy is an excellent way to treat acute sprains and strains and treat muscle tension, pain, and spasm. Cold therapy also helps reduce injury-related pain and swelling. These products are affordable for individual use but the high quality craftsmanship and ease of washing, sanitizing, and reusing make them ideal for the medical professional.
