A school bag is an essential accessory for students of all ages, serving as a practical and functional way to carry books, stationery, and other school supplies. It is designed to withstand the demands of daily use while providing comfort and organization for students' belongings.

The design of a school bag typically includes a main compartment that offers ample space for textbooks, notebooks, folders, and other large items. This compartment may feature a zipper closure or a flap with buckle or snap closures to secure the contents. Inside the main compartment, there are usually smaller pockets or compartments for organizing smaller items such as pens, pencils, calculators, and personal belongings.
