Intelligent One Way Airlock: Dual channel automatic exhaust design allows carbon dioxide produced during fermentation to escape while blocking outside oxygen , creating a stable anaerobic environment and effectively avoiding fermentation failure and jar bursting
Convenient Silicone Stopper Switch: After fermentation , no need to change lids . Simply take out the airlock and seal the hole with the included silicone stopper to switch to sealed storage mode , locking in fermented flavor and keeping pickles fresh longer
