This is the current model Kalita copper pot 700, without hinges. The appropriate capacity is 500ml. - Purchased in October 2024. - Has never been heated directly over a flame. - I think there is some degree of use. Some practice is required for pouring, but once you get used to it, it's easier to pour than with a thin spout. Also, I saw on YouTube that some people remove the clear lacquer from the surface and let it age. (This pot is as it was when purchased)
