Pure Copper Fukuju Hon-nuri Kunpu Fukujudo Gyokuro Tea Caddy

This is a Fukujudo pure copper Fukuju Hon-nuri Kunpu Gyokuro tea caddy purchased from a second-hand shop. It has not been used, but I have listed it as near unused because it appears to be old. I believe the inside is clean. Dimensions: Height 7 cm, Diameter 6.4 cm. Thank you for your consideration.
