I'm not very knowledgeable, so I would appreciate it if you could judge based on the photos. It's a teacup that is 9 centimeters tall, with a top diameter of 15.5 centimeters, a bottom diameter of 6 centimeters, and a base height of 1.5 centimeters. I thought it might be from Ise, but I'm not sure because there's no box. It has never been used, so I hope it can be of use to someone.
