Post-it Recycled Super Sticky Notes help support a better future by using recycled paper and feature a unique adhesive with twice the sticking power so your notes will stick securely to more surfaces. Now you can stick your notes where they'll really get noticed - like monitors, windows, doors and walls. Move your notes with you throughout the day. The 4" x 4" size is perfect for reminders or a short to-do list. Super Sticky Notes hold longer and stronger than original notes yet remove cleanly. Super Sticky Post-it Notes and their paperboard packaging are recyclable, and the paper in Post-it Notes is sourced from certified, renewable and responsibly managed forests.
