Very good to put in mylar bags for long term storage.

It is a very good product, and arrived on time and in good conditions.

Nice item for your long term storage needs.

Perfect for my dehydrated items. Need order mored.

These mylar bags are great, thick and sturdy. They seal well. The only problem is that they are missing oxygen absorbers! The package says "80" (8 vacuum sealed bags of 10) but there are only 9 in each sealed bag. Sigh.

As far as I know they work. Not sure how you’re supposed to know if it is working? We toss one in a jar with dry goods to keep fresh.

I like the different sizes and the labels that they came with and that the bags can be sealed with a clothes iron. I'm going to put rice, flower, cornmeal etc, in them.
