This item was stored in the storage shed at my parents' house. It was given to me by an acquaintance who used to make pottery with their own kiln. I tested it for leaks by filling it with water, and there were no leaks at all. I think it can be used in various ways, not just as a flower vase. Please note that this is a handmade item and is not perfectly round. Also, it is a used item and has been stored at home. We appreciate your understanding. m(_ _)m Diameter: Approximately 41cm Height: Approximately 15.5cm
