Instant Hot and Cold Packs

Packs are activated with just enough impact to make accidental activation difficult. Durable, heavy plastic bags prevent leakage and are see-through, allowing you to immediately recognize if the product has been activated.
Instant Cold Packs get cold in three seconds for treatment of swelling, burns, nose bleeds, headaches and other injuries. Remain cold (less than 40°F) for a minimum of 15 mins.
Instant Heat Packs heat instantly (three seconds) for treating muscle injuries, sprains and more. Packs stay above 125°F for a minimum of 15 mins.
