This is an old teacup I found in my home storage. It's an unusual brown color, giving it a modern impression. Size: Approximately 11cm in diameter x 6cm in height There are irregularities, bumps, and small bubble-like spots throughout, which appear to be from the manufacturing process. The foot of the cup is rough. It's difficult to see in the photos, but the brown color of the base is not uniform; some parts are a darker brown, while others are slightly lighter and reddish. The inside appears to be vermilion in some photos, but it's the same dark brown as the outside. I think the third and fourth photos are the most accurate representation of the color. There is not much evidence of use. Please consider purchasing if you understand that this is an old item. Thank you for looking.
