Purchase date unknown. I believe this is a large teacup. Diameter: 9cm, Height: 7.5cm I considered using it as a small bowl, but looking at the actual construction, I think it's more of a "ippuku-wan" (a small bowl for a quick break) rather than a kobachi (small bowl). I used it once or twice and washed it. Since it's from Harumi Kurihara's shop, I think it's made by an artist, but I don't know for sure because there's no mark. It's quite old, but looking at the texture of the foot, I suspect it might be an early work by a now-famous artist. The mishima (powdered slip) texture is beautiful, so how about it if you like it? I also have other kitchen items for sale. Please comment if you'd like to combine purchases. I may be able to offer a discount on shipping. #mimuracucina #HarumiKurihara #Teacup #RiceBowl #SmallBowl #PowderedSlip Color: White Type: Tableware Set
