This item is from the late 1950s to the early 1960s. The lid has cork on the inside. The bottom says "Seyei." Is this Seyei (瀬栄) Pottery? I'm not sure, but it's a very Showa retro-style ceramic piece. It looks retro even just displayed. Size: Approximately 7.5 cm in diameter, 11.7 cm in height. There is some dirt, unevenness on the bottom, and a small chip that is not very noticeable (see photo 2). Please understand this.
