  • Publication number: 20090123685
    Abstract: A memo pad includes a stack of memo sheets, each memo sheet including an inscribing portion, a pair of supporting portions, a pair of adhering portions, and a pair of adhesive layers. The adhesive layers are applied to the bottom side of the adhering portions such that an upper one of the memo sheets is adhered releasably to a lower one in the stack. When a memo sheet is removed from the memo pad, and the adhesive layers are used to attach the adhering portions to a supporting surface, the supporting portions are disposed to support the inscribing portion such that the inscribing portion is raised relative to the supporting surface, thereby configuring the memo sheet to present a three-dimensional appearance.
