This is a very beautiful wine-red glass. The shape is also beautiful, and it's a piece that makes you want to look at it. I purchased it in Kurashiki as Kurashiki glass, but I don't remember if it was a work by Mr. Otani, and I don't have the box or anything. The size is about the size of your palm, and it seems good for beer, wine, or of course, tea. I've included photos with a measuring tape. I hope you'll use this glass every day. Thank you.
