I purchased this several years ago from a physical store in the United States. I was renovating my home at the time and, without much thought, bought a few of these in different colors. However, I ended up not using this one, so I'd like to pass it on to someone who can. I think it's something you can't easily find in Japan. It has been stored in a cardboard box for a long time. Although it is unused, I am looking forward to your purchase if you understand that it is a used item. It is slightly trapezoidal. Top diameter: Approximately 29 cm Bottom diameter: Approximately 31 cm Height: Approximately 22 cm
