Murasakino, Kumi-dashi Teacup, Hagi-yaki, NIPPON CRAFT This item was stored at my grandmother's house. Based on my amateur research, it appears to be Hagi-yaki pottery. I cannot be certain... I would appreciate it if someone who knows more, or someone who is still interested, would consider purchasing. Please refrain from purchasing if you are overly concerned about details. ● Size Diameter: Approximately 8 cm Height: Approximately 7 cm
