120 Packs 500CC 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

Nice and functional, drop a few in a Mylar bag with bulk material (food, rice,beans,etc) and they should be good to go for years.

No complaints

These are great to help keep packages dry

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.

I really like they come in 10 per bag, 12 thick plastic bags for my 120 absorber order of 500cc. I use one in a gallon or quart mylar bag to preserve the food for years. I only seal about 3 mylar bags at a time, and I put the other 7 unused absorbers in a quart mylar bag and iron seal to preserve them for future use, NOT in a mason jar, as I found they don't protect totally the unused absorbers reliably. I recently sealed up nuts, flour, and cereals I bought as extras to eat to eat a year or so from now, as prices are going up dramatically each year, and I end up saving around 30% on my food costs a year, a big deal. And I can buy 6 or 12 of an item, mylar each, and get a bigger savings on buying the quantity pricing deal. I bought these before, and haven't had one not work totally like other 500cc I got in the past where I get a not seal (of course, I may not have ironed the mylar bag enough when I was starting out sealing mylar bags years ago.) Besides keeping the foods like-new fresh with the air out, but the absorber-in mylar bags are much thicker than the packages foods come in, and it protects from insect or small animal infestations I was getting sometimes.

I don't know. They are those little packets you put in dry goods to suck out the oxygen. I am told they work. People who store things seem to like them.

Easy to use, legible font, no leaky packs.

Repurchase.. work great
