OEM Post-it Pop-up Refill Notes are designed for use in Post-it Pop-up Note Dispensers (sold separately). The alternating color design offers the convenience of grabbing just one note with one hand, keeping your ideas looking fresh. Accordion-style notes pop up one at a time from a specially designed dispenser, ensuring Post-it Notes are always at your fingertips. Each pad includes 90 sheets, perfect for notes, numbers, and lists, and is part of the Ultra Collection. The repositionable adhesive won't mark paper or other surfaces, and the paper used comes from well-managed forests where trees are replanted.
