Medline Alcohol Prep Pads are disposable medical devices that are designed to be used for skin preparation before injections or other medical procedures. These pads are made of a non-woven material that is saturated with 70% isopropyl alcohol, which is a disinfectant that effectively kills germs and bacteria on the skin's surface. The single-use packets are compact and portable, making them perfect to carry in a car or include in a first aid kit at home.
