Hi Carol, Aren't they great! They have an airlock mechanism that makes fermentation easier and more controllable. The supplier I got mine from years ago is no longer in existence, however other places do sell them. I also have a few larger tradictional fermentation crocks that work on a similar mechanism (mine are Harsch brand)- but they are made for large batches of fermenting - 10-20 pounds. It's nice to have these smaller jars to work with. Jacinta
The pickle jars ….tell me about these jars?
