Abstract

A cellulosic fibrous structure product having one or more plies. At least one of the plies has one or more unembossed areas, and the one or more unembossed area has a macroscopic first surface and a macroscopic second surface. The fibrous structure product also has a first wall which forms vertices with the first surface and the second surface. In addition, the first wall and the second surface form a top side wall angle of from about 90° to about 140°.

Claims (25)
