This is a gift, but I'm selling it because I don't use it. It was purchased at a shop called Sabita in Sapporo for 8800 yen. It was made by Sayuri Eguchi, a writer living in Ebetsu City, and it seems to be popular. It's a tea cozy for Chinese tea sets, and it won't fit a regular-sized teapot for black tea. Please refer to the second photo for the size. The height was about 12cm. The previous owner only had a black tea teapot and seemed to enjoy it as interior decoration, so the condition is good. It seems to be difficult to obtain because the artist is popular. It will be sent via Takkyubin Compact.
