The existing cotton balls on the market all need to be immersed in the liquid medicine, and the second use is easy to cause the liquid medicine pollution. The disinfectants we often use are alcohol and iodine, and people are troubled because they need them at the same time. This design can improve these situations, you don't need a potion at all, because a potion capsule is designed on the other end of the cotton ball. One can squeeze it gently and rupture the liquid film attached to the plastic tube of the cotton ball to flow into the cotton ball to impregnate it for people to use.
