After using the cotton swab, the user is used to break the cotton swab to remind others that the cotton swab has been used. According to this behavior habit, a dent is added in the middle of the cotton swab to remind the user to fold one end of the used cotton swab in advance. The remaining unused part is temporarily stored on the bumpy cotton swab cover, and can also be left for others to continue using to keep the cotton swab clean and sanitary. Users need to carry out other operations when using cotton swabs. At this time, the cotton swabs are thrown away, causing waste, and there is no place to put them. At this time, cotton swabs can also be temporarily placed at the place where the top of the cotton swab box is concave-convex, and the cotton swabs are not easy to roll off, and the gentle concave-convex undulation is not easy to accumulate dust, thus reducing the waste of cotton swabs. At the same time, the original shape of the lid is broken, so that the shape of the lid can be interesting, and the boring feeling of the process of purchasing cotton swabs is reduced.
