Keep your insulin safe in the FRIO DUO Wallet. These wallets keep your insulin cool without the need for any refrigerated products like ice. The cooling properties come from the evaporation of water and keep its low temperatures for over 2 days, even in challenging environments. Giving you the ability to go days without having to worry about re-activating. They are also easy to use, only taking 5-15 minutes to activate. This light and compact version of the FRIO Wallet gives you the ability to keep multiple pens or vials safe while on the go. In it protect up to five (5) insulin pens or six (6) 10ml vials of insulin and syringes. To activate the FRIO wallet, immerse it in cold water for 5-15 minutes. Soaking times vary, please refer to instruction leaflet. Crystals contained in the panels of the wallet then expand into a gel, which remains cool for up to several days — relying on the process of evaporation for cooling. Just towel dry the outside and it’s ready to go! For continuous use put the FRIO back in water for a maximum of 2 minutes. It can be reactivated over and over again.
