    1. Best oxygen absorber on the market.  star rating

      Posted by Glenda on May 8th 2020

      We are sold. My son and I are both into dry canning. I purchased some for him and some for myself. He called and told me that they sit an wait for the pot on the jar seal. (Him and his youngest son). We are all impressed with the convenience and product. I am still learning how to keep the absorbers I don't use right then. A few loses, but nothing major.

    2. Super Oxygen Absorber Combo Pack  star rating

      Posted by Sandy Baker on Oct 13th 2019

      This is the first time I purchased this large of a package. I really like their products they are easy to use, and with this combo it's the right size and the right price. Great Value. I'm finding I really like the dry canning for long term food storage so I'll be back to get some more soon. The shipping is quick! Thank you
