Post-it Super Sticky Notes feature 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. In a perfect 3" x 3" size for reminders or a short to-do list, Super Sticky Notes hold longer and stronger than original notes, yet remove cleanly. Vibrant Electric Yellow Notes help get your message across. All Post-it Notes are recyclable, and the paper in Post-it Notes is sourced from certified, renewable and responsibly managed forests.
