Regarding the chopstick case: I believe the inner handle area is for toothpicks, but I'm not certain of its correct use. I think it's an interesting item, so if you like Japanese antiques and old tools, please enjoy it in your own way. The age, material, and intended use are all unknown. Please be aware of this. There are many scratches on the back. I will clean it as much as possible before shipping. Dimensions: Height: 38cm (inside: 4.2cm and 31cm) Width: 10.5cm (inside: 7.6cm and 8.2cm) Depth: 5cm (inside: 4.2cm) If you are looking for antiques, Showa retro items, Japanese accessories, or Oriental items, please see here: #momono_kura_Japanese_items #momono_kura_tableware 259u3 8080
