This collapsible rigid gift box combines a flat-pack structure with a polished retail presentation. Thick greyboard is wrapped in printed paper, with a vivid pink exterior, metallic gold interior, and contrasting black side panels. A rectangular die-cut window in the hinged cover allows partial product visibility and can be supplied open or patched with clear film. Gold foil-style graphics add a refined decorative finish, while scored gusset panels enable quick assembly and compact storage. The fold-over cover provides a neat closure without an exposed handle, ribbon, or loose accessory. Suitable for festive gifts, confectionery, cosmetics, apparel accessories, and curated retail sets, the box can be customized in size, paper texture, color, artwork, foil tone, window shape, insert layout, and closure details. The flat-pack design can reduce storage and transport volume while retaining a rigid presentation format.
