Good quality products at a great price. I have a couple of airlocks that I use for beer and wine making, but I needed these for making sauerkraut and other fermented vegetables. I’m going to drill holes in plastic mason jar lids and use these on 1/2 gallon mason jars.

The Airlocks are super clear with exception of the top which is white. Did have a problem with the inside part of one of the Airlock. But after 2 emails to Customer Service, a new Airlock was sent for no extra cost.

One of them came broken. Cheap enough but still
