B5 folder for PP College rubber notebooks

The folder on an elastic band College Line with a plastic frame 500μm thick and a textile extension is light and roomy. When empty, the folder does not have its own volume - its width changes depending on how full it is, which allows you to optimize the space in the school bag. A dense elastic band without a "memory effect" allows you to fix the folder in a closed form in various ways. Workbooks and a Kite school diary can be placed in the folder, as well as notebooks of non-standard sizes up to 26 cm high.
