OEM Post-it Pop-up Refill Notes are designed for use in Post-it Pop-up Note Dispensers (sold separately). These accordion-style notes pop up one at a time, keeping Post-it Notes readily accessible. The pastel pads are ideal for jotting down notes, numbers, and lists. With repositionable adhesive, they won't mark paper or other surfaces. The paper used is sourced from well-managed forests where trees are replanted.
