The listing says. 25L which would be just over 8oz but the description says 12.3 oz. What is the actual oz size?

This was one of the most frustrating parts of buying these jars. The glass is clearly stamped "370". 370 is not 250, a quarter liter. The math isn't very difficult. But the box says 1/4 liter. Clearly the box people and the glass people are not the same people.

Where are these made?

These Weck jars are made in Germany.

Will these work in a sous vide?

Probably not. This container is only about 3 inches tall and 4 inches wide

One of the jars arrived cracked, who do I contact for a replacement?

It might be easier to return it and place a new order.
