Cotton wool ball

Cotton wool balls are small, spherical absorbent pads made from cotton or synthetic fibers, primarily used to apply topical medications or gently cleanse body areas by absorbing fluids. They are commonly employed in wound care, minor skin treatments, or as part of clinical procedures where precise absorption is needed.

These devices are generally single-use and designed for both home and professional healthcare settings. Regulation varies by jurisdiction, but they are typically classified as low-risk medical devices due to their simple construction and intended use.
