Post-it Pop-up Refill Notes are designed for use in Post-it Pop-up Note Dispensers (sold separately). Self-adhesive notes offer 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 dispenser (sold separately), keeping Post-it Notes at your fingertips. Pads are the perfect size for notes, numbers and lists. Repositionable adhesive won't mark paper and other surfaces. Paper used comes from well-managed forests where trees are replanted. Each pad contains 100 sheets.
