One Black Wireless Mouse · Surface Roughness Contrast

SUBJECT
One unbranded black wireless mouse with a rounded matte shell, a narrow glossy black strip running along its center, and one small scroll wheel seated within that strip. Keep both finishes equally black in their underlying color.

COMPOSITION
Use an elevated three-quarter view showing the top and image-right flank. Point the mouse's front toward the upper-left of the image, with its rear toward the lower-right. Center the entire mouse on a plain warm-gray tabletop with generous space around it.

STYLE GUIDE
1. Shape & line
Build the mouse from a low oval body with smoothly rounded shoulders; make the central strip follow the body's curvature and keep its boundaries crisp enough to distinguish the two finishes without adding a raised border.

2. Color & light
Place a broad rectangular light above the image-left side. Show its pale reflection as a clearly bounded, curved ribbon on the glossy strip and as a broad, softly fading patch on the adjacent matte shell; retain readable dark tones on the image-right flank.

3. Texture & material
Give the shell a fine, subdued plastic grain that gently breaks up its diffuse highlight. Keep the glossy strip smooth with a coherent reflection, and render the scroll wheel as soft rubber with a few readable transverse grooves.

4. Composition
Keep the complete mouse sharply readable at a moderate size in the frame. Let a soft contact shadow extend toward the lower-right across the tabletop, and leave the surrounding surface quiet so the adjacent matte and glossy reflections remain the focal comparison.

PRIORITY
Preserve the requested identity, count, action, composition and output settings. Apply the style rules within those constraints; a style reference must not replace the subject or layout. Within the style: Prioritize the visible reflection difference between adjacent surfaces of the same black color.

AVOID
Avoid making the matte shell chalky gray or the glossy strip metallic.

OUTPUT
Produce one photorealistic product-reference image in a square 1:1 aspect ratio, without lettering, logos, captions, or watermarks.

SELF-CHECK
Check that one image-left light produces a bounded reflection on the glossy strip and a soft patch on the matte shell.
