The most common use of cotton swabs is to clean or touch the ear canal and/or remove earwax, although this is not a medically recommended way to remove earwax. Cotton swabs are also often used outside the field of personal hygiene: they are usually used for the construction of plastic model boxes, for various applications in the decoration or painting process.

Medical cotton swab is suitable for cleaning and disinfection of skin or trauma. The cotton swab is coated immediately, and the hollow rod structure is used to store the liquid medicine, so that the cotton swab itself has the liquid medicine, which is convenient and fast. It is suitable for hospitals, families, schools, hotels and also very suitable for travel.
