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 is 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 would appreciate it if someone who understands its age would purchase it. Thank you for looking.
