Abstract
A swab is described formed of a paper stick having opposite ends of less paper density than the rest of the stick. An absorbent covering such as cotton is placed around the ends. The stick is obtained by rolling a paper having left and right edges harmonically cut with at least two amplitude maxima and at least one amplitude minima. Softer stick ends are achieved through this structural arrangement. A cut paper used for forming the swab stick and a manufacturing process are also described.
