    1. Love the variety  star rating

      Posted by Barbara D Steskal on Oct 24th 2021

      Since I order a variety of sizes of mylar bags and have a variety of sizes of Mason jars, this variety pack of OAs is perfect for me.

    2. So easy to keep fresh longer  star rating

      Posted by Donna Gonzales-Vera on Aug 6th 2018

      Got information with my package that detailed the best process for success.
      And now I know which size oxygen absorber works with what size jar. I pulled out all my large jars with dry foods, herbs, etc. and added absorbers to them. Put the leftovers in a small jar. I am more confident using these absorbers now.
