Post-it Super Sticky Notes hold stronger and longer than most self-adhesive notes so you can be sure that your message gets through. Have the confidence to leave important messages on multiple surfaces including computer monitors, office doors, and walls. Repositionable adhesive won't mark paper and other surfaces. Notes are lined with a 1/4" light blue grid for precision messages. Paper used comes from well-managed forests where trees are replanted. Each pad contains 90 sheets.
