I purchased this several years ago from a physical store in the United States. I bought it without much thought as I was renovating my home, but I have no use for it, so I'm offering it to someone who can use it. I think it's something you can't easily find in Japan. It has been stored in a cardboard box the whole time. It is unused, but I am looking forward to purchases from those who understand that it is a used item. It is slightly trapezoidal. Top diameter: Approximately 28 cm Bottom diameter: Approximately 31 cm Height: Approximately 22 cm
