Iga-yaki tea bowl. Since the stamped tea bowls are not sold, they have a premium. I purchased it for about 5,000 yen at a stylish shop near Ebisu Station that sells Iga-yaki pottery from Hasegama kiln and tea bowls. I loved the smooth feel of the surface when I held it, as well as the texture and atmosphere. The grayish pale green color is lovely. Small chip present. Those who are not particular may not mind it so much. For those who can do gold repair, etc. An antique I have cherished, a one-of-a-kind item.
