Our 50cc oxygen absorbers are of the highest quality and factory vacuum-sealed to ensure freshness. 

Oxygen absorbers start working (absorbing oxygen) from the atmosphere as soon as exposed to air, i.e. as soon as the package is opened. 

50cc oxygen absorbers are the perfect size for our 9cm x 10cm pouch and 15cm x 15cm bags, but can also be used with smaller bags, or for other applications.  

Simply place one oxygen absorber in your bag, with contents, press out as much air as possible and seal the top using a normal iron or heat-sealer.  

We sell only genuine OxyFree 504A oxygen absorbers, factory sealed and with OxyEye pink-to-blue oxygen indicator. Beware of sellers who show the genuine OxyFree product in their photos, but send inferior generic absorbers. 

Please see our other auctions for OxyFree absorbers in larger sizes; 100cc, 300cc and 2,000cc.
