This work is inspired by the cabinet in the home. In the frame, various drawers are set to load documents or clothing in different categories. However, the schoolbags or backpacks we use can only be used in a fixed format designed by the manufacturer. However, we have to search for items in a large backpack or carry a large outer bag that bears weight, which also makes us sweat to hold our back, so we designed a drawer-type strap that can be attached to a variety of styles, shapes, or sizes. Bags to cater to the needs of users.
