An industrial design packaging specification sheet for [a penguin-shaped packaging box], based on the reference photo. A centered heroic 3D rendering showcases realistic materials, commercial-grade finishes, and soft studio lighting with subtle drop shadows. Surrounding the center are technical orthographic views: front, side, top, bottom, oblique perspective, and an unfolded flat dieline layout. Include pencil sketches of structural frame lines, crease lines, seam details, and dimension arrows in millimeters. Add handwritten callout annotations detailing materials and surface finishes (matte, glossy print, paper, plastic), accompanied by color swatches. Clean sketchbook paper background, combining realistic 3D product rendering with technical pencil sketch drafting.
