Questions & Answers

When not in use, how should they be stored? Is it necessary to keep them cool? Also, do they have an expiration date? Can they sit for a year and still be fine? ty! ?

Last year, I bought a few of these and used them exactly one year later. I've had a few in the freezer since then, as well as a few on a pantry shelf. They've been sitting at room temperature for a year, and I just refroze a couple of them a few days ago, and they're still functional. So, no, they don't expire, and yes, they can be left unattended for a year.

Is this still useful when submerged in water?

We've never submerged them in water, but they've been reused numerous times without issue.

For perishable food shipping, this is an excellent option

5/5

This is fantastic. I use them to ship perishable food items because they keep the items cool and are light weight, lowering shipping costs. I buy a lot of things.
