100 Packs 100CC Food Grade Oxygen Absorbers (10 Pack in Individual Vacuum Bag ) , Oxygen Absorbers For Long Term Food Storage with Oxygen Indicator , Works in Mylar Bags, Mason Jars, and Vacuum Bags

These work extremely well.I've been using them for the last year. The amount you get for the price is really great. Super easy to use no instructions needed.

Came in perfect working order. Used to seal rice and beans in jars. Worked great.

They work when sealing in mylar bags or using in Mason jars!

I know these are 500cc, but they seem a little small. I’m using them to help preserve my freeze dried foods and they will work for my smaller packages, but I will probably have to use two in my larger packages until I can get a larger size ordered. I like they come in 10 count packages and have an oxygen sensor included, to let you know if they are still good or not. I wish they came in a zip lock bag as a whole with the individual packets inside their smaller packages, but once you open the main package, there is no way to close it. You either need to put it in a different package or use a clip to close the current bag. They seem to be of good quality and function. Hopefully the foods I have used them on will store and keep well.

So far I am happy with these, they are well packaged in in small bags to keep them active and fresh as I use them. it will help keep my food fresh over longer periods of time, to have extra food stored in case of unplanned emergencys, like winter storms, & financial hardships.

Works very well for me. The packaging is great. As described. Thank you

Came sealed. Does it's job efficiently.

as described well packaged, sets of ten have group O2 indicator, all are good
