The dispenser includes an elongated body having a pair of like confronting hollow body shells. Each of the body shells has a pair of adjacent longitudinal edges interconnected by an integral hinge. There are also confronting longitudinal edges. Each body shell has a cross-section of an isosceles triangle whereby the body has a square cross-section. The body shells also have end walls with confronting pairs thereof having means for retaining such end walls in confronting relation. An integral cutting member is hingedly connected to the confronting longitudinal edge of one of the body shells by an integral hinge and lies closely adjacent to a side wall of the other body shell.
