I purchased these from a kiln in Kurayoshi, Tottori, several decades ago when I was sightseeing there. I fell in love with them at first sight because of their perfect size and the subtle differences in color and shape of each one, but I've kept them displayed in my cupboard almost unused because I thought they were too precious to use.
