Abstract: A printing material supply may include a body to contain a printing material, a latch pivotably coupled to the body by a living hinge and a latch protector. The latch protector may include a structure coupled to and projecting from the body so as to contact a packaging surface of a package to inhibit creep of the latch about the living hinge when the printing material supply is contained within the packaging.

Abstract: The present invention comprises a method for the instruction of handwriting through the use of cartoon items. Certain cartoons and other drawings may be introduced and students asked to reproduce the cartoon items a number of times; until a desired proficiency is reached. Subsequently, the student may be made aware that a portion or all of the cartoon item also includes a handwriting element. The student may then be instructed in the reproduction of the handwriting element alone. Through this method the student may acquire the necessary skills to reproduce the handwriting element alone, or in combination with other handwriting elements, to achieve proficiency at reproducing the handwriting element. The end result being that handwriting may be learned efficiently in a manner that retains the students' interest.
