Minimalist Storage Rack Sale Poster

[Format] Professional e-commerce product main image, square 1:1, minimal black-and-white Japanese-style promo with stark typography. [Colors] Plain off-white ground (#f7f7f5); pure black display type and hairline rules; the only color comes from the product's black wheels; no frame border. [Layout] Top-left a "6.18 | Official Flagship Store" lockup over a thin rule; the rack left-of-centre; a right-hand column with title, sub-line and price; a second rule near the bottom with dates lower-left and an oversized claim lower-right. A whisper of shadow under the castor wheels grounds the unit, and the wire grid stays crisp against the blank ground. [Subject] A three-tier white wire storage rack on black castor wheels, each tier a lift-off wire basket, photographed straight-on against the blank ground with a whisper of shadow. No people. [Headline] Right column: "Multi-tier floor storage rack" in heavy black; a lighter sub-line "Large capacity, free tiering"; then "$39.9" with its currency mark. Bottom-left: "5.29 - 5.31, early access savings" in small caps. Bottom-right: an enormous "2nd item half price" in heavy black caps. [Mood] Airy, orderly and value-led; stark monochrome minimalism where the typography does all the selling. Every element is stripped back so the price and the half-price claim dominate at thumbnail size.
