Roll of sanitary pad / sanitary pad

Many females randomly throw away their used sanitary napkin in the toilet,
which not only makes other peoples feel it very unhygienic and dirty but also
make the cleaning staffs clean very painfully.“Roll of sanitary napkin”design
is to add a plastic rope on the bottom of the sanitary napkin. It let the female
roll to the used sanitary napkin before throwing it to the rubbish bins. This
small change will not affect the normal use of sanitary napkins as well as will
be more humane.
