I'm not familiar with those, but here's what I like to do: When I get a new 100 pk of O2 absorbers, I put them into sandwich baggies with 20 absorbers in a bag. I take a straw and insert it into the corner then start zipping on the opposite corner (towards the straw). Zip it all the way to the straw. Now compress the bag manually to get as much air out as you can. Once you've done that, while still compressing it, take a deep breath, exhale and then inhale as much as you can from the straw. This will suck almost all of the air out. Pull the straw out with your teeth and immediately close the bag the rest of the way. You can then store the bags and only have to expose a small amount at a time when you need to get some out. Repeat the above procedure to reseal the bag.
