Very durable and arrived quickly

Works

I keep a bunch in my emergency kit in the jeep. I store bottles of liquid and aerosols in them to keep from bursting in extreme temps. These are also great for keeping the temp for a while for your food. Glad I found them but wish I got a bigger size. Pay attention to that.

These are great to have on hand. I keep a few in my car for when I get hot or cold food items while shopping. I want to see if I can use it to ship treats to my friend and her kids.

First off these bags do exactly what they say they will. They keep hot things cold - to a point. The biggest issue with the bags is their size. Because of the materials there is very little flex in them. They hold less than you think they will and will require multiple bags or another solution altogether. If you need to keep medications at a safe temp on a trip or to safely pack some small things for overnight shipping these will probably work well. As general use containers they're very limited due to size. I also wish they were more reusable. If you aren't shipping rubber bands, or different adhesives will sever you better than the built in strip.

Customers are really impressed when they receive their plants in the mail with these. They really appreciate the extra protection these provide. Got a few nice reviews because of them.

Doesn't keep my daughter's food warm for school

These bags are very nice to have if you have to transport colder items for short distances! They are pretty thin, that said, and don't retain cold for very long without an ice pack of some kind. Would work well if you deliver with Doordash, Uber Eats, Instacart, whatever, if you don't have much cooler space and need to keep more items cold here and there.
