Dual-Ended Lipstick 12.12 Sale Banner

[Format] Professional e-commerce product main image, square 1:1, sweet pastel beauty-promo style. Dreamy pink and powder-blue palette with playful rounded type. [Colors] Background pale blue melting into blush pink (#cfe6f7 to #f7d9e3) with translucent bubbles and a glossy pink puddle. Accent rose red for price flash and ribbons. No frame border. [Layout] Dark corner ribbons top both corners. A two-line headline is centred near the top with a bracketed gift line under it. Two hero lipsticks lean diagonally through the middle, lip-swatch cards stacking on the right. A price tag sits lower-left, a rose banner crosses the width, and two gift panels share the bottom strip. [Subject] A pink gradient dual-ended lipstick set: one open bullet showing a soft rosy shade, a second tube behind with a silver band and clear cap. To the right, two close-up lip photos - one matte velvet pink, one glassy gloss. Bubbles float up over a pink gloss puddle. No people. [Headline] Big dark characters: "Dual-Ended, Dual Effects - Three Shades in One Stick", with a bracketed line "Free Full-Size Lip Glaze with Purchase" where the gift words turn rose-red. Top right: "TIME: 12.12 20:00-12.15 23:59". Swatch tags "Matte" and "Glossy"; left tag "As low as $39.5 per piece"; rose banner "Add to Cart Now - Join for Member Gifts". [Badges] The bottom strip splits into two offers: "New-Member Gift" with a mini lipstick and powder puffs, and "Gift Over $300" with a pink compact and a bubble "Free over $300". [Mood] Flirty, gift-driven and sweet; cotton-candy gradients and glossy lips for a festival sale.
