It's a small expander. I think it's a rare item that you don't see very often. It's made of metal and is a Showa-retro item. My family kept it carefully stored in a box. There is some age-related dullness, but there is no noticeable damage. As it is a vintage item, please understand its condition before purchasing (^-^) [Bundle Discount] ★ Items priced at 300 yen: 100 yen off per item from the second item onwards.
