I have a collection of various Benesse Challenge supplements from 4th to 6th grade, mostly unused. There are a total of 14 items as shown in the photos. Upon checking, accessories like stickers and 3D glasses are unused. Everything is printed in vibrant colors, which should delight children. The kanji + word dictionary, shown in the top right, shows signs of use and has some stains on the back cover. I didn't find any writing inside. Please forgive any oversight. The others are almost unused or in a ready-to-use condition. Please understand that these are items stored at home and are not new. 47 Prefectures Puzzle, Historical Figures, English Dictionary Stars, Moon, Division of Decimals, Adventure in the Body Autumn Break, Winter Break, 5th Grade
