Each Thermx Instant Ice Cooling Pack contains a sealed inner pouch of purified water and a crystalline cooling agent (commonly ammonium nitrate or urea-based compounds) designed to produce an endothermic reaction when mixed. The outer layer is a durable, puncture-resistant polyethylene/nylon composite with a non-woven fabric finish for comfortable short-term contact. Packaging and materials meet standard single-use medical cold pack specifications.

1. Expose the pack and firmly squeeze or strike the center to rupture the inner water pouch.
2. Shake or knead the pack to mix contents and activate cooling (the temperature drops within seconds).
3. Place a thin cloth or towel between the pack and skin—do not apply directly to bare skin.
4. Apply to the affected area for up to 20 minutes. Remove for 20–40 minutes before reapplying if further cooling is needed.
5. Discard after single use. Do not attempt to re-freeze or refill.

Thermx Instant Ice Cooling Packs are ideal for athletes, coaches, parents, outdoor enthusiasts, travel and workplace first aid kits, EMTs, and anyone needing fast, portable cold therapy. Use for sprains, strains, bruises, swelling, fever relief, insect bites and immediate post-injury care when refrigeration isn’t available.

Caution: For external use only. Do not puncture inner pouch except to activate. Avoid direct prolonged contact with skin—always use a cloth barrier. Not recommended for people with cold hypersensitivity, circulatory problems, diabetes-related neuropathy, or for infants without medical advice. If contents come into contact with skin or eyes, rinse thoroughly with water and seek medical attention if irritation persists. If ingested, seek medical help immediately and show product label.

Storage: Store at room temperature away from direct sunlight. Keep out of reach of children and pets. Single-use only; dispose of according to local regulations. Do not place in freezer or microwave.
