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. With lines to keep your notes straight, 4" x 4" size is perfect for capturing important details or list-making. Super Sticky Notes hold longer and stronger than original notes yet remove cleanly. The New York collection includes colors inspired by the skyline, stone and steel. Super Sticky Post-it Notes are recyclable, and the paper in Post-it Notes is sourced from certified, renewable and responsibly managed forests.
