A clean studio product photograph of the Deep Sleep Mask in solid black (#000000) against a neutral background. The image showcases the full-face coverage design with the contoured eye cups and adjustable strap visible. The background is likely warm cream (#F9F6F2) or pure white (#FFFFFF), creating strong contrast with the black mask. Lighting highlights the silk sheen and smooth texture of the 23 momme mulberry silk. The composition is straight-on or slightly angled for dimension.
