There were 3 or 4 pieces in that last firing with a similar glazing, and the ones like this and that chawan went quickly. I'm guessing more like them will show up if you keep checking his etsy.
I got another cup at the same time, because two can ship almost as cheaply as one. It's a subtle dark shino
more variegated than rainbowed, here showing quite a few colors over the lip to the lighter interior
and there's a little swirl in a few places to add pattern to the color
and best of all, a wonderful size for the majority of my teapots, about 4 oz.
