A menstrual belt is a rectangular belt that women could put toilet paper in during their menstruation in the past when there were no sanitary napkins, and it could play a good role in fixing the toilet paper so that it would not slip off easily. The toilet paper is placed in the menstrual band, and the band can be fixed on both sides of the large crotch area, so that it does not easily fall off. Women can change the toilet paper regularly during menstruation, menstrual blood does not flow out easily and pollute the underwear, and it is easy for women to move around. Most menstrual belts are made of breathable cotton fabric, which is good for women’s health. Nowadays, women are using sanitary napkins, which have replaced the role of sanitary belts, and the effect is much better than sanitary belts and more convenient to use.
