Randoseru are the boxy, hard-sided leather backpacks carried by elementary school children in Japan. The term "randoseru" derived from the old Dutch word "ransel" meaning military backpacks used in the 19th century. The randoseru became really popular after the WWII and now they are carried by virtually every Japanese elementary school student.
Ikuta's randoseru are known for their high quality materials and top-notch construction. They require more than 200 manufacturing processes and the company does every one of those steps in-house. With the straps extending to 26.5", the randoseru can be comfortably carried by an adult.
