Easy fermentation with a pickling airlock lid that automatically "burps" air out but allows none inside!
Fitted for a canning jar, this unique one-way valve, self-venting design makes it a foolproof way to ferment probiotic sauerkraut, pickles, kimchi, etc...
The self-venting lid means you don't need to babysit the fermentation process so the delicious contents don't spoil.
Screw band still needed and not included // mason jar not included
