I received this as a bonus at a Tohoku festival. It's unused. I've kept it stored in a box for a long time. It's an eyepatch of Date Masamune. Length: 5cm, Width: 5.7cm, Weight: 50g It's made with quite intricate detail, and has the weight and texture of copper. I haven't seen this for sale anywhere else, so I think it's quite rare. ⭐︎Instant purchase and purchase without comment are welcome.
