I found this while organizing a storehouse. It's from the Taisho to Showa eras and I believe it's a very valuable item made of pure tin. The diameter of the container is about 8 cm, and the height is about 4.5 cm. With the lid on, the diameter is about 8.5 cm and the height is about 4.8 cm. Inside the wooden box, there's a polishing powder for care and care instructions. (I'll leave it as is because it looks like it might fall apart if I open it.) Since it's old, I'd appreciate it if someone who understands its age would purchase it. Thank you for looking.
