PackFreshUSA: 100 Pack - 200cc Oxygen Absorber Packs - Food Grade - Non-Toxic - Food Preservation - Long-Term Food Storage Guide Included

Good price

Bought these thinking they would be in packets of ten but they were all in one single packet. Although they're suppose to be used with one gallon containers I use them in one qrt containers to be on the safe side. The small monitor which comes in the packet was pink which means they were good to go, however, after placing them inside my qrt jars I had expected the lid to pop down but it did not so I'm not sure if they're doing what they're suppose to. I did place them in an airtight jar once opened and only took them out for immediate use. The monitor thingy turned blue after opening the first time & continues to be blue in the stored airtight jar.

I have not yet used, however the literature and tips are very helpful. I'm sure to be pleased with the performance.

Thank you and it was on time

Packs came in 2 separate vacuum sealed pouches that held very well. I opened and used the absorbens in one pouch. The indicator dot on the unopened pack is still pink a 6 weeks after I received them.

Was having trouble finding a 200cc oxygen absorber these where perfect at a great price. Arrived in a vacuum sealed pack opened them up used a couple then vacuum sealed them into a mason jar.

Will serve the purpose quite well.

Total waste of money. packing food for long term storage.Had cereal & oatmeal in mylar bags with sealed tops, added a couple of oxygen absorbers expecting to have bags vacuumed packed after a couple of days, but nothing.I have done this before with success, these batch I received, did nothing.It was a total waste of money. : (
