Post-it Pop-up Refill Notes are designed for use in Post-it Pop-up Note Dispensers (sold separately). Accordion-style notes pop up one at a time from a specially designed dispenser (sold separately), keeping Post-it Notes at your fingertips. Pastel 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.
