Frio Insulin Wallet,
Verified Purchase(What is this?)
This review is from: FRIO Duo Insulin Cool Wallet PURPLE (Personal Care)
Did not use in the end- also bought another one. May be helpful to specify- for insulin pens, how many it will hold. The Small Wallet held everything I required.
Incredibly useful for long distance air travel and keeping insulin chilled during the whole journey. Good that it can be reused too.
