Vertical 9:16 TikTok-style video, shot on smartphone.
Scene 1: A young American female teacher stands by a messy desk piled with laptop, planner, water bottle, pencil case and notebook. She looks a bit stressed.
Next to the pile is a light blue structured canvas tote bag with zipper and detachable strap, exactly like the reference product photos.
Scene 2: Quick jump cut — now the desk is clean, all items are gone, and the same tote stands upright on the desk, zipped closed.
Scene 3: Close shot of her grabbing the handles, clipping on the shoulder strap and wearing it crossbody as she walks toward the classroom door, smiling.
The bag stays closed the whole time. No clear interior or overhead shots looking into the bag.
Bright natural lighting, slight handheld phone camera shake, 8–9 seconds.
