VacYaYa 3000CC(30-Pack) Food Grade Oxygen Absorbers Packets for Home Made Jerky and Long Term Food Storage, Stored in Vacuum Bag and 3 Times Oxygen Absorption Capacity

They don't work at all. I used them with flour in a 5 gal mylar bag. Its been a month and the bag still has oxygen in them. I put the unused ones in a zip lock bag and in a month they are not removing oxygen. Don't waste your money.

Make sure you have all your intended Jars or vacuum bags set up before you open this products bag they come in, to not waste them.

Good for food preservation

I should have known by the price, but this ad is just flat out lying. These o2 absorbers are NOT 3000cc. They're not even 1000cc. They MIGHT be 100cc. What a scam!!

Great product I bought 2 packages and one was not sealed

The package that the oxygen Absorbers were in had a hole in it, and all of the absorbers were compromised, and I sent it back

It works good

I purchased a few packages of these to help keep moisture out of long term storage foods in 5 gallon buckets. While they work great, at first...Don't buy them unless you plan to use ALL of them, at once. I used MAYBE 6 of the pack? Saved the rest for changing them out every so often, as we open the buckets of food often for "rotating pantry stock" type foods.Even with me vacuum sealing the unused/remainder in a new bag, and storing them in a dark, cool pantry-2 months later, they're completely hard as a rock. IF these were sealed individually or were able to be resealed completely, and kept from absorbing oxygen somehow, the price would be excellent. Unfortunately, I was a bit tight on cash and kind of biting my tongue trying to justify spending this much when I did. I figured it was to keep our food investments longer, fresher, and safe to eat....so it was worth it.Until I realized I just paid $18 for 6 of the packets. Hard pressed to buy again :( I need smaller counts at an affordable price, or individually packaged. Very disappointed :(.
