N95 Respirator Mask Flu Cold Protection Pack

[Format] Professional e-commerce product main image, square 1:1, urgent high-contrast promotional style. Hard-selling retail typography on a clean white ground with red emphasis blocks and a photographic product cluster. [Colors] Pure white "#ffffff" background; signal red "#d92b1f" for the stamp word, the huge percentage and the bottom block; solid black bars and box; soft grey shadows. No frame border. [Layout] A tight text stack runs down the left third; the product cluster fills the right half at a slight angle. A two-character red stamp word sits in the top-right corner, a black rounded bar underlines the first headline line, the giant red percentage dominates mid-left, and a solid red rectangular block anchors the bottom-left corner. [Subject] No people. A black retail box standing angled behind a white cup-style respirator mask laid flat, the mask featuring a yellow exhalation valve printed with the 3M logo and relaxed elastic head straps; a second white mask peeks out behind the box edge, all softly shadowed on white. [Headline] Top-left bold black text reads "Fight Flu and Colds"; below it a black bar with white text "Every box includes 5 free N95 filter cartridges". Then "Filtration efficiency ≥" in black, then "95%" in enormous heavy red digits. The top-right corner stamp reads "IN STOCK" in large red characters. The bottom-left red block carries white lines "Free express shipping" and "Ships on the 10th of the first month". [Mood] Urgent, confident and deal-forward; stark red-on-white retail energy that stays readable at thumbnail size.
