I purchased this at a tea shop several years ago and have used it a few times. It is a flat tea bowl used for summer tea ceremonies. There is an impressed mark, but I don't know the details. I'm not sure if it's a crane or a heron, but it's a very lovely design. Please only purchase if you don't mind. *There was a faint stain on the unglazed part on the back of the bowl. I've listed it as "no noticeable scratches or dirt" because I don't think it would be noticeable during normal use. There is no original box, so I will wrap it in bubble wrap for shipping. Please only purchase if you understand this.
