I got the 1 gallon 60 count Mylar bags with 60 count oxigen absorbers.
The bags.
They are a bit thin. You can see through the layers so some light can still get in even when sealed. I'm packing them in buckets so that's not a huge issue for my use.
They seal just fine using a food saver or iron.
They seem to be durable for there size and price.
If your not going to be keeping your sealed bags in dark containers (buckets) I would sugest getting thicker bags.
Oxigen absorbers.
They come 3 packs of 20 per pack (60 total)
They do have the oxigen eye in each pack that lets you know if there good or not.
However when I got mine the eyes were 3 diffrent shades (still in the good range)
That tells me that maybe they were packed at diffrent times.
All that I have used seem to be working as they should.
However I did add 2 per full bag to make sure they were oxigen free.

All in all its a good deal for the price.

I bought both the 1 gallon mylar bags and the 5 gallon mylar bags. The best and most convenient way to store whatever may be needed at another time. Just make sure before you seal them up, you first put in one or two oxygen absorbers. Then slowly squeeze out as much air as possible by rolling up the bag towards the opening. Fold the opening of the bag over once or twice, and press them shut with an iron. That's it. LOCKED IN FOR GOOD. The more air you are able to get out of the bag before sealing it up, the longer shelf live the food you have stored in them will last. Definitely the way to go

I haven't opened these bags as of this writing. We are just starting to prepare for long term storage and are still in the learning stage. Concerned about Oxygen Absorbers because once package is opened you have to store the unopened oxygen Absorbers to keep them in a usable state. In previewing videos on long term storage to have to have the Mylar bags filled and ready to seal before you start adding the oxygen absorbers. Thus to you have to have the Oxygen Absorbers in a storage container to keep them from going bad. What it doesn't say on this package is that to test to see if the oxygen absorber is good, you simply feel the bag. If the bag is soft the absorber is good; If the bag has harden the Oxygen absorber is bad.

Worked well for me, convenient to have on hand for when dehydrating apples or other foods. I've found that keeping the opened bag of O2 absorbers in a glass jar with lid and rim works beautifully for preserving these long term (they've lasted a few years using this method). The thickness of mylar was just fine for my needs. Thanks!

Oh and if you want a phenomenal mid-winter treat for yourself or kiddos, thinly slice some apples (honey crisp are amazing but galas and jonathans or jonagolds work well too), soak in water with a heaping teaspoon of ascorbic acid (can also use lemon). Drain the water and then dry using your fav dehydrator. Mine is the cheap round one with four plastic drying things (things? You know, trays - sheesh, middle aged brain here). Anyway, I can usually get about four apples' worth on the trays. Sprinkle with cinnamon (OK, I do put a hint, just a hint, of sugar in), dry the apples for 12 hours or so, enjoy the amazing apple-cinnamon aroma as the apples are dehydrating. Once they've reached the desired crispness, let them cool off for a few minutes, then place in your handy dandy mylar bag, pop in an oxygen absorber, crank up your iron and seal two inches or so with the iron. And then save bag for a rainy day, or a cold wintery day when the kids are whining and you are desperate for a little joy.

Fast delivery, Good way to preserve food. Great value. excellent item
