Red Toolbox Year-End Mega Sale

[Format] Professional e-commerce product main image, square 1:1, clean industrial studio style with a bold year-end sale banner. [Colors] Background is a textured grey concrete wall (#8a8a8a range) with soft vignetting and dark tropical leaves entering from the top-right corner; the hero product is glossy candy red (#d81e1e); the bottom promo band is a warm gradient from orange-red (#e8452c) to deep red (#b01212) with white and yellow type. No frame border. [Layout] The toolbox sits centered slightly left, filling the middle two-thirds of the frame; a scalloped event badge overlaps the top-left corner; the bottom fifth is a full-width gradient banner carrying the price and coupon copy in large display type. [Subject] No people. A red powder-coated cantilever steel toolbox with its lid open in five stacked tiers, a chrome draw latch on the front and a black moulded carry handle on top; the open tray holds a fanned set of polished chrome combination wrenches and pliers, with crisp studio highlights running along the glossy enamel surfaces. [Headline] Top-left corner: a white-and-pink scalloped seal reading "12.12" over "Year-End Mega Sale". Bottom banner: a small white script label "Hot Deal", then a huge yellow "129" with a small "$" prefix, followed by a bold white rounded-sans line "Extra $50 Off With Coupon". [Badges] The pink scalloped event seal in the top-left corner is the only badge. [Mood] Bold, punchy year-end-sale energy; glossy red hardware glowing against cool industrial grey.
