Cotton ball

Cotton balls are absorbent, non-sterile spherical masses made from cotton or synthetic fibers used as swabs to apply medications or remove fluids from various body parts. They are commonly used in both healthcare settings and at home for wound care, applying ointments, or cleaning skin.

These devices are typically supplied as single-use items and are generally available over-the-counter without a prescription. They are not classified as medical devices requiring special regulatory approval in most jurisdictions.
