What is the name of the Japanese student handbag

The randsel school bag was first introduced to foreign countries in the late 19th century, and through years of development and improvement, it has gradually developed into a modern style. randsel school bags have a hard-shell structure that protects books and stationery from being damaged, and breathable and comfortable straps that reduce the burden on the back, which is ideal for students to walk with the bag for a long period of time to and from school.
