The Post-it® Super Sticky Notes have a unique adhesive so your notes will stick securely to more surfaces. Now you can stick your notes where they'll really get noticed...like monitors, doors, and walls! The Post-it Super Sticky Notes feature 2x the sticking power than regular Post-it Notes. Use for notes or reminders on doors, windows, or walls. Unique adhesive reliably sticks and re-sticks so your message can stay front and centre and allows you to move your notes with you throughout the day.
