Post-it Super Sticky Pop-up Note refills stick practically anywhere with revolutionary adhesive technology. Put your notes where they'll get noticed - like monitors, doors and walls. Pop-up feature offers the convenience of grabbing just one note, with just one hand. The accordion-style notes pop up one at a time from a specially designed pop-up dispenser (sold separately), keeping the notes at your fingertips. The paper in Post-it Notes is sourced from certified, renewable and responsibly managed forests. Each pad contains 90 sheets.
