This is a three-tiered jubako (tiered food container) that was purchased previously for osechi (New Year's food) and has been stored since. The material is plastic. There are minor scratches and scuffs from storage, but I couldn't find any major damage or cracks. External dimensions: Length and width: 19.5 x 19.5 cm Height: Approximately 17.5 cm Please note that these measurements are approximate due to being taken by a non-professional. Please understand that this is a used, home-stored item, and refrain from purchasing if you are concerned. The item will be wrapped in bubble wrap and then shipped in a cardboard box. I'm happy to add more images or answer any questions, so please feel free to ask.
