400cc Oxygen Absorbers for Food Storage - 100 Count (20x Packs of 5) - for Long Term Food Storage & Survival, Mylar Bags, Canning, Harvest Right Freeze Dryer, Dehydrated, and Preserved Foods

These are wonderful and perfect for anyone who freeze dried their own food. I use these in my Mylar bags whenever I package my freeze dried food and they keep it fresh. Simply open the package and throw them in. It is important to note that once exposed to air you cannot reseal them to use at another time as they do not work as well. I learned this after packaging some food using previously opened ones and they did not work as well. Overall they are great for the price!

These are probably not 400cc but I used a few each and they worked as expected. Sucked the bags down tight.

Perfect for long term food preservation.

These oxygen absorbers do just what they're supposed to do. If you're a prepper you need these. They also work great in drawers, toolboxes and closets. Highly recommend

Couldn't do our freeze drying without this item. No one could. It is essential to keep your items from taking in any moisture which is the enemy of something freeze-dried. They are super easy to use, and you just chuck on or two into the jar, mylar bag, or whatever you are storing your freeze-dried items in then seal. They function as designed and so far, we have not had any failures with them, and you almost forget you have them in the jar or bag.

Arrived promptly & was exactly as advertised
