This red child's backpack, called a randoseru, contains various school supplies and other items. The bag is red leather or vinyl, in a rectangular shape. The red color is traditionally used by girls, while boys favor black backpacks. The metal clasp, on which the word "Atomu" is inscriped in katakana, is at the bottom to attach a front flap, which folds back to reveal an orange vinyl-lined interior with various pockets and one large compartment for books. There is a beige trim on the reverse of the bag with metal button adornments all over. A key chain that is attached at the side represents a plastic cartoon character of a small man with pointed, elf-like ears and a black helmet decorated with red fly's eyes; he is also wearing a green shirt and a white belt.
The items inside the interior flap include:
-One small blue, plastic-covered, wallet-sized, empty photo album, decorated with anime characters on the front.
-One small plastic packet of facial tissues with a brown and white cartoon dog and the words "ABC wan wan inukun" on the front. The back features the words "Hone hone, daisuki ["I love bones"]; open; Planning by Kyoda Creation," with another picture of the dog in a yellow box with bones. The side reads "Frisky Tot."
-One packet of twenty-five 13.2 cm x 13.2 cm Hello Kitty (Sanrio Co.)–themed origami papers in a plastic sleeve with instructions on the reverse. The origami papers have a 1976 and 1989 copyright date, and are made in Japan. They originally cost ¥150.
One of the smaller front pockets contains a small coloring book with girl cartoon characters on front and inside, made in Japan and with a price tag for ¥70 on the back.
