This is a set of 5 mini trays for the Obon festival. They are made of plastic, so they are lightweight and easy to clean. Size: 16 x 16 cm (length and width) There is some minor staining on the sides, but it's not very noticeable. Please check the photos. I don't remember using them, and they have been stored at home for a long time. Please refrain from purchasing if you are concerned about minor details. They will be placed in a plastic bag and shipped via Yu-Packet Post with simple packaging. Thank you.
