黑色长条形扁平带状物件

超宽横向产品摄影图，纯白背景上水平居中放置一根黑色长条状扁平物件，类似橡胶或塑料材质的带状零件；中央主体为细长扁平黑色条带，表面哑光并带轻微反光，边缘略有起伏；两端各有一段略宽的斜切端头，端头表面有多条竖向凹槽和棱线，左侧端头上缘斜向下收，右侧端头斜向上收；画面无人物、无文字，物件横向占满构图，正面平视，均匀柔和棚拍灯光，黑白对比干净，画幅比例约16:1。

Ultra-wide horizontal product photography on a pure white background, a long flat black strip-like object placed horizontally and centered, resembling a rubber or plastic band component; the central body is a slender flat black band with a matte surface and slight sheen, subtly uneven edges; each end has a slightly wider angled end cap with multiple vertical grooves and ridges, the left cap sloping downward at the top edge and the right cap sloping upward; no people, no text, the object spans the composition horizontally, frontal eye-level view, even soft studio lighting, clean black-and-white contrast, aspect ratio approximately 16:1.
