Design me a sample box

AQS Industries is a 3-month old company based in Navi Mumbai, India. We are developing an Ecommerce marketplace primarily for interior designers, decorators and architects. The ecommerce website will have materials - like wood veneers, wood laminates, glass, tiles, solid surfaces, fabrics - used in the interiors of residential and commercial spaces. This will help designers in choosing the right materials for their projects on a single platform. After selection, the user (designer) can order the samples of the materials shortlisted according to the moodboard of his project, before placing an order. The sample box will be free and every user would get a personalized box with his name/company tag on his first order. The sample box would be such that the outside cover would be retained by the user while the inner case is returned after a specified time. The additional requirements of the box are, 1. Since some materials like glass are fragile, the case should be sturdy; 2. Since the samples would be provided as per each users requirement, it should be modular type; and 3. The box should be durable yet economic.
