Thank you! This is a movie theater-exclusive popcorn box commemorating the movie "Doraemon: Nobita's Earth Symphony"! I used it only once at the movie theater. I wiped it clean! It's clean, but it's a used item, so please refrain from purchasing if you are concerned. No claims and no returns, please. I haven't made it "reserved" according to Mercari rules. The person who presses the purchase button will be given priority in any case. I hope it reaches someone who needs it! Also, I have a Crayon Shin-chan popcorn box. Please take a look if you'd like!
