Antique? It's a vintage bentwood lunch box. According to my family, it's over 50 years old. It has a beautiful amber color, but the lid and other parts are still in good condition. It hasn't been used for food, but rather as a container for small items. Approximate size: Diameter: 14.8cm Height: 9cm This is an old item stored at home, so please check the images and understand before purchasing.
