Store 500cc Oxygen Absorbers at room temperature (5°C to 30°C), away from direct sunlight. They should be stored in their sealed package or a glass jar with a gasketed lid. Select the smallest glass jar possible to minimise the oxygen the absorbers will remove from the jar. 500cc Oxygen Absorbers in a well-sealed container will cause the lid to pop down. The shelf life of a 500cc Oxygen Absorber is up to 18 months.
