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. The Rio de Janeiro Color Collection is expressive and dramatic with colors celebrating this Brazilian metropolis. Super Sticky Post-it Notes are recyclable, and the paper in Post-it Notes is sourced from certified, renewable and responsibly managed forests.
