Oxy-Sorb 300cc Oxygen Absorbers for Food Storage (20 Pack) - Preserving Food Freshness with Food Grade Oxygen Absorbers for Long-Term Storage

These are great to remove oxygen in mylar bags.

good so far, wish more information was provided for first time buyers

Would have liked some instructions to be included, For example one time use only or can they be used again. And once you open the air tight bag do they need to be used or can they be put in a baggie for later use.?

...like it will work. I'll know for sure when I open the mylar bags and go to eat the food.

I expect a good product, we're only using it for emergency use storage.

Great size for small packs of jerky

i opened these and they absorber the oxygen out of the room i almost died. had to seal them up in mason jar keep them form destroying the world.

Perfect packets for my dehydrated vegetable storage.
