Water-Soluble Colored Pencils Promo Display

[Format] Professional e-commerce product main image, square 1:1, dense product-display style for art supplies. [Colors] Clean white upper ground; a purple-blue gradient band along the bottom; a black metal tin; rainbow-dipped pencil tips; blue pills and a red arrow tag; no frame border. [Layout] A blue free-shipping chip top-left; three blue pills stacked top-right; the open tin lying diagonally across the centre; a red downward-arrow tag lower-left; a gradient bottom band holding title, subtitle and a price roundel. The tin hinge catches a small highlight, and a faint rainbow reflection from the tips shows on the lid's inner lip. [Subject] An open black metal storage tin holding two neat rows of water-soluble colored pencils with white barrels and rainbow-dipped tips, arranged fanned outward so every hue shows. No people. [Headline] Blue pills: "Highly water-soluble", "Pure vivid color", "Smooth laydown". Red arrow tag: "Price cut: $20 off". Bottom band: "Officially licensed, authentic import" in blue caps over "Water-soluble colored pencils" in heavy black, with a purple roundel reading "Promo $59". [Badges] The blue corner chip "Free shipping" at the top-left edge. [Mood] Colorful, energetic and stationery-store bright; a rainbow focal point with hard-working promo callouts. Saturated tips against the black tin create maximum hue contrast for a scroll-stopping swatch effect.
