发明名称 Paper stack protection device
摘要 A paper stack protection device is disclosed which has a triangular shaped pocket designed to accept a corner of a stack of papers. A staple through the pocket and the corner of a paper stack secures the pocket to the stack of papers. The top and bottom sides of the pocket provide a long fold back line along the hypotenuse of the front and back sides of the pocket so that the first and last sheets of the stack of papers are inhibited from tearing away from the stack.
