These are the best jars for sourdough starter! I didn’t need the whole box, so selling those I don’t need - they aren’t used. I love them! I use this style and the tulip jar and both work great. Weck jars are made in Germany. This comes with the sealed glass lid and a plastic lid too. Item 743 Height: 5 3/4″ Opening: 3 7/8″ Volume: 28.7 fl. oz.
