A versatile container for the workspace and a customized compartment for documents. Be aware that the typical dimensions of standard sheets are 9 centimeters by 9 centimeters square, indicating that the interior space of the storage box should be slightly larger than this measurement to accommodate the paper comfortably. However, as shown in the photograph, the size is actually smaller than what one might expect based on common standards.
