This item was purchased by my parents and kept in storage for many years. The box inscription mentions "well" (井戸) and "box writing," so it appears to be an Ido chawan (well tea bowl). The artist seems to be Kim Eung-han of Leecheon Pottery (利川陶窯　金応漢). It appears to be old and has been stored for many years, so there are some stains on the box, but it is unused. The photos were taken in natural light. Size: Diameter: Approximately 14 cm Height: Approximately 8 cm Weight: 288g I am not an expert, but I believe it is a simple, rustic tea bowl. Thank you.
