ABSTRACT:
An artist's crayon or chalk is provided with a cover which is made of a sheet of axially oriented polymer, the sheet having one side provided by a plurality of arcuate regions separated by cusps, the regions forming tear tabs. By gripping a tear tab and tearing, the axially oriented polymer will tear in a substantially straight line thus enabling the required amount of cover to be removed from the pastel. The cover may initially be provided in a self-adhesive form adhered to a peel-off backing sheet.
