Abstract:
A notepad includes multiple sheets that are arranged into a stack. Each sheet has a first major face, a second major face, and a perimeter edge at which each of the first and second major faces terminate. The notepad also includes an adhesive disposed on a portion of the second major face of each sheet such that the portion of the second major face of each sheet releasably adheres to a corresponding portion of the first major face of an underlying sheet. The portion being disposed with the adhesive lies adjacent to a portion of the perimeter edge of a corresponding sheet for forming a releasably bonded side of the stack. Also, the stack is twisted about a common central axis of the sheets present therein such that the notepad has a spiral shape.
