The parallelepiped-shaped box has a maple wood structure externally covered with thuja feather; on both sides there are handles and brass inlays, while on the front there is a lock also in brass. The interior, covered in red morocco with golden friezes and green paper, is arranged on two levels: in the first, which has four extractable elements, the largest of which hides a large compartment underneath, there are custom-made housings for the various work tools; the second level is divided into four compartments, of which the two largest support two drawers (one for spools, another undivided and hosting various yarns). The entire internal part of the lid is occupied by a mirror. A further secret drawer located on the right side, at the base of the box, can be accessed from the outside; in it there is a small mahogany desk covered in leather, inside which there are still contained, in the appropriate spaces, a white writing paper and a glass ink holder. In various points of the box appear paper labels with the name of the textile emporium where it was purchased: “Au Pere de Famille / Rue Thionville, (Dauphine.) / Au coin de Celle / d'Anjou / à Paris”, sometimes supplemented by: “Magazin de Fils / Epingles et Aiguilles”. Under the main compartment there is a label with the complete list of materials on sale at the shop itself.
