This is a cute cherry blossom lunch box. Perfect for New Year's dishes, cherry blossom viewing, outings, picnics, etc. (^^) The exact material is unknown, but I believe it's likely made of synthetic resin (plastic). I apologize for the vague explanation, but please consider this if you understand. It's new and unused, but has been stored at home for many years. Therefore, there is some minor soiling, but I will carefully wipe it clean before shipping. It does not come with a box. Please refrain from purchasing if you are looking for a perfect item. Thank you for your understanding and consideration.
