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. The 4" x 6" size with 1/4" light blue grid lines on a white background is perfect for technical sketches, capturing important details or list making. Super Sticky Notes hold longer and stronger than original notes, yet remove cleanly. All Post-it Notes are recyclable, and the paper in Post-it Notes is sourced from certified, renewable and responsibly managed forests.
