I used this a little after purchasing it, but it has been stored in a cupboard for a long time. When you press the knob and close it tightly, it is unlikely to leak. A part of the bottom is white, but I think there is no problem with use. If you don't mind, please consider purchasing. I am also selling other types. Size Diameter: Approximately 14 cm (Including spout and handle) Diameter: Approximately 19 cm Height: Approximately 17.5 cm (including knob)
