The size is approximately 22 x 22 x 17 (cm). It holds a lot. It's made of lightweight plastic. It was useful not only for New Year's, but also for the Doll Festival, Children's Day, sports days, and other events. Both the outside and inside are black, and it's easy to use because it has no patterns or designs. I disinfected it with Pastryze just in case. (Pastryze is not included in the items for sale.)
