【Widely Use】: The set contains 100 pieces(10x PCS of 10) of 300CC Oxygen Absorbers, suitable for most mylar bags, canning lids, etc., cookies, snacks, spices, cereals, flour, pasta, etc. Unlike other Oxygen Absorbers on the market, half of the effect is wasted in the sealing process (maintain oxygen for up to 5 hours, so don't worry about no effect, but the oxygen inhalation speed is slow).
