Lightweight Hard-Shell Suitcase with Silent Spinner Wheels

[Format] Professional e-commerce product main image, square 1:1, clean travel-gear advertising style with annotation callouts and a fresh green backdrop. [Colors] A soft sage-green textured wall (#a8c39a range) with dappled leaf shadows; the silver-and-black suitcase is the hero; a cream podium at the base; a pale-yellow price block and a green bottom band. No frame border. [Layout] The suitcase stands angled on a cream plinth centre-left, rendered large. Three hand-style annotations with curved black arrows point at features: one on the left, one upper right, one lower right. The bottom quarter splits into a cream price card on the left and a green service band on the right with two white icon chips. [Subject] A silver ribbed hard-shell carry-on suitcase with black corner guards, a telescopic handle, a black side handle and four black spinner wheels, shown in three-quarter view standing on its wheels; crisp product light with a soft cast shadow on the plinth. [Headline] Annotations in dark characters with arrow doodles: "Three-digit combination lock" pointing at the lock, "Lightweight wear-resistant shell" at the shell, "Silent spinner wheels" at the wheels. Cream card: "Final price 199 yuan" with "199" huge in black. Green band: "SF Express free shipping" and "Lifetime warranty" in white, each beside a small circular icon. [Badges] Two small white circular icons inside the green service band. [Mood] Practical, tidy and trip-ready; fresh sage calm with confident silver hardware, annotation-led clarity at thumbnail size.
