We make dozens of rigid box prototypes everyday. This satin-covered simple rigid box is one of them, which includes a knob to hold the elastic on the lid, to keep the box closed. Amongst different types of closures, colours, textures and finishing options, this is a standard box requirement, often asked by our discerning customers who love a traditional closure to the box. Silk and Satin are available in over 11 colours to choose from. Special colours and closures can be made on request.
