Review: Didn't work for me - I'm not sure if there is an expiration date on these but I've had them for a while, but they were unopened; vacuum sealed in their original package and when I opened them, they didn't work. Not sure if it was manufacturers defect or expiration date issue. It would be nice if they had indicators on them to let you know if they are still good or not.
Review: Harvest Right trusts them and so do I - I freeze dry food for both human and my pet's consumption, so it's very important to me that I can rely on the mylar bags I package it in as well as the oxygen absorbers I use. I've purchased these FreshUS oxygen absorbers through desertcart three times now and once directly from Harvest Right's site. The fact that Harvest Right has enough faith in them to stake their reputation on them gives me a high degree of confidence in the quality of this brand, and the fact that they're made in the USA by a company that's specialized in food packaging since 1993 is definitely a huge plus. Getting the absorbers in packets of ten rather than one large bag makes it convenient for me to get the amount I need out and then reseal the package without exposing a large number of them to air. This keeps the bulk of the order safe from exposure to air until needed. To keep the oxygen absorbers from going bad, package up everything you want to store first, then cut open the oxygen absorber packet and pop the absorbers into the top of your containers. If you have unused absorbers left, just flatten the packet to push air out, then reseal the packet with your heat sealer to keep them fresh. The color of the indicator within each packet should be pink if the absorbers are good and purple if they're bad. Another way to check them is by feel though - if they're good they'll feel soft, and you can hear the granules inside roll around like sand. If they've gone bad the absorber will feel harder and the granules inside will have started to clump together. Don't use those! Feeling a little warmth when handling a mylar bag you've sealed with one of these absorbers is another indicator that the absorber is good and is absorbing oxygen. Don't expect the oxygen absorber to shrink or compress a mylar bag down though. You might see a little compression, but don't think that's an indicator that the absorber is working or not working! These absorb oxygen, not air. The atmosphere is 21% oxygen with the rest being nitrogen and other gasses, so there will still be "air" in your bag unless you're using a mason jar with vacuum sealer. It's oxygen along with moisture and light that causes food spoilage though, so don't be worried about bag compression, these do what they're supposed to do.

## Questions & Answers

**Q: How big are these and could they be folded to fit in a 2 liter bottle?**
A: 2 Liter plastic bottles will not protect from oxygen passthrough in long term food storage scenarios.  You might consider a container with less oxygen passthrough.  Glass or mylar bags.  300cc bags are recommended for a gallon so a 200cc bag is likely a better fit for a 2 liter bottle.

**Q: what is shelf life of packets?**
A: I reseal my bags because they get hard fairly quickly. I've had sealed bags for a year that are still good. I buy in bulk. I wouldn't trust storing them in just the clear bags they come in because over time air can get in. I store my original sealed bags of o2 absorbers in either jars or a sealed Mylar bag.

**Q: Vienen divididos**
A: vienen 10 por paquete / 10 unit per pack

**Q: Does it matter where you put them in the jar, for example ,oo the top or on the bottom**
A: I put them on the top of the food and seal them immediately with a vacuum sealer
