Review on 50-Pack 8” X 12” Mylar Bags With 300Cc Oxygen Absorbers And Heat Sealable Rounded Corners - Free Long-Term Food Storage Guide Included. by James Cabot

These work great! I love that they come in a nice kit w/ bags and oxygen absorbers together, and it is really smart that they pre-package the oxygen absorbers in packs of 10, so you don't have to worry about wasting them if you don't use them all at once, or trying to find an alternate method of storing your left over absorbers. The pre-made tear notches are great too, makes opening the bags really easy. I sealed with a foodsaver using the "seal only" mode. Note: these mylar bags (like most) won't vacuum seal very easy due to the completely smooth interior of the bag - lots of tricks to get them to vacuum seal on the internet, but remember if you are using the right amount of oxygen absorber, you likely don't have to vacuum all the air out first. Quart size bags are slightly larger than a quart, which allows you to put an actual quart worth of food inside, and still be able to seal it, which is awesome.They sealed just fine with a foodsaver on seal only mode - following some advice from a youtube video, I double sealed the opening, but I am not sure that was necessary, as there was no air leak after the first seal. Easy instructions come with it - read them for some good tips. Seal in lots of 10, and get all of your food in the bags first before opening the oxygen absorbers, and you will be just fine. Note that each pack of 10 oxygen absorbers has a pink indicator so you can see if it has been exposed to oxygen - they turn dark blue/purple once they've been exposed.Again, great product, works amazing. Very impressed with the quality feel of the bags, and the quick delivery. I will use again, for sure. Highly recommended!
