According to the market survey, most women do not take any shielding measures when using discarded sanitary napkins, especially in public toilets, in order to reduce the chance of menstrual blood exposure in the air and make sanitary napkins more safe to handle. We carried out a certain design on the edge of the sanitary napkin. When the sanitary napkin is discarded, pull the thin rope at the front of the sanitary napkin, and the sanitary napkin will be automatically wrapped, and convenient for safe and sanitary disposal.
