Based on the Koransha logo, this item is likely from the 1960s. Therefore, it's approximately 50 years old. According to my mother, who kept it at her home, it wasn't used very often (only for guests). There might be small, inconspicuous scratches (I couldn't find any upon inspection), but overall, the condition seems quite good. Please be aware that this is a used item and is quite old. Size: Opening diameter: Approximately 7cm Height: Approximately 5.8cm This is a small teacup, holding about 100cc when filled to about 80%.
