Mother-K Cotton Buds are made from cotton and paper, without the use of any plastics. The tips are made from high quality cotton that is soft to touch, while the stick is made from paper that can be bent softly, making it safe to use on children. These cotton buds can be used to remove pus or foreign substances from children's ears, nose and bellybutton. This cotton bud has two types of tips - one tip smooth, and the other tip corrugated. The tip with the corrugated end helps remove foreign substances from children's ears and nose more efficiently.
