Abstract
Abstract A sanitary napkin having adhesive peel-off strips at the ends of the napkin for securing the napkin to an undergarment of a wearer. The peel-off strips with a pile or soft plastic surface finish are scored or cut to permit peel-off tabs on the garment side of an absorbent cover for the napkin to be removed by peeling toward the longitudinal center of the napkin. Thus, the napkin, whether in the form of a mini-pad or a regular size pad, is a relatively inconspicuous device that can be attached relatively indiscernibly to the undergarment of the wearer.
