Frio insulin cooling wallets keep your insulin and other sensitive medications at a safe temperature.
Your Frio will keep in-use insulin within safe temperatures of 18-26°C (64.4-78.8°F) for a minimum of 45 hours, even in a constant environmental temperature of 37.8°C (100°F).
To activate your FRIO simply immerse the inner wallet in water for the time specified on the instructions which can be as little as 5 minutes. Then pat the inner wallet dry with a towel and insert it into the outer cover. Then you are good to go!
