The Nanki Mihama Kiln closed in 2006, and it seems that Mihama-yaki is no longer produced, making this a rare and valuable item. It's a beautiful blue. Light blue, sky blue, pastel blue, a soft blue. I think it's a color with a deep flavor that subtly changes depending on the light. The cup is stamped with "mi" (for Mihama-yaki) on the bottom. (See image 4) The roundness of the cup fits comfortably in your hand. It's stylish for wine, craft beer, or cold sake, and also for juice or tea. I liked the beautiful blue and bought it, displaying it after taking it out of the box. I have never used it, but please understand that it has been stored at a private residence. There are no cracks, chips, or breaks. There is only one black spot on the bottom, but it was there when I bought it and is apparently due to the firing process. (See image 5) Cup: Diameter approx. 6cm, Height approx. 13.5cm (including the foot) It will be shipped via anonymous delivery. Thank you. #MihamaYaki #FreeCup #Goblet #Valuable #Rare
