These instant ice packs measure 6 by 4.5 inches each and come in a bulk pack of 25 units. They are designed for single-use cold therapy on injuries, sprains, strains, or minor bruises. The pack activates by simply squeezing or striking the inner pouch, causing an immediate endothermic reaction that produces a cooling temperature without pre-freezing. Each pack remains cold for approximately 20 to 30 minutes, offering sufficient time to reduce swelling and numb localized pain. The outer material is a durable, non-woven fabric that resists tearing during activation and handling.

Inside, the chemical mixture consists of ammonium nitrate and water separated by a thin barrier; once broken, the reaction quickly drops the temperature. There are no gel refills or additional components, making disposal straightforward after use. The dimensions are compact enough to fit in a first-aid kit, gym bag, or travel pouch while still providing adequate coverage for joints like ankles, wrists, knees, or elbows. These cold packs are suitable for athletes, outdoor workers, caregivers, and households needing a ready-to-use cooling source for acute injuries. They work as a temporary measure before professional medical attention is sought. The packs are not rechargeable and should not be reused, but the case of 25 ensures a steady supply for multiple incidents or for use in clinics, sports teams, and school health offices. The texture is dry to the touch once the pack is activated, with the chilled surface conforming gently around the injured area. They are lightweight and portable, with no risk of freezer burn or water leakage. The affordability of the bulk pack makes it a practical choice for those who require frequent access to instant cold therapy without investing in reusable gel packs or electric cooling units. The product provides consistent performance across each pack, with reliable activation and sustained cooling. It is advisable to wrap the pack in a thin cloth or towel before placing it on skin to avoid frostbite or discomfort. For best results, use as soon as possible after injury to help manage swelling and discomfort.
