Post-it Pop-up Refill Notes are designed for use in Post-it Pop-up Note Dispensers. Pop-up notes offer the convenience of grabbing just one note, with just one hand. 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 90 sheets. Note colors coordinate with the included 3D Iris insert for pop-up dispensers.
