A squared matte-white perfume bottle stands centered on a seamless light-gray cyclorama. The cap is a matching rounded block, joined by a short cylinder. The body has a fine ceramic grain and no glossy highlight band. Soft top-side light, a short clean contact shadow fading to the back right. 100mm macro, f/8, the whole product in focus, crisp edges, pure background. Square frame, bottle slightly left of center, even commercial margin around it. No label text, logo, watermark, clutter, or a second product.
