This document provides information about tampons, including their design, materials, and safety. It discusses the different types of tampons, such as coiled and applicator tampons, and how they are manufactured. Absorbency levels for tampons ranging from junior to ultra are defined based on gram weight. The main materials used in modern tampons are cotton, rayon, or a mixture.
