Notes are kept tidy and orderly with the original Canary Yellow Post-it Notes featuring lines. Notes that are removable and self-stick adhere firmly and neatly. A brief to-do list or reminders work well with the 4" x 4" size. Canary Yellow Notes are recognizable and eye-catching, and they aid in communicating your message. Post-it Notes can be recycled, and the paper used to make them comes from responsibly managed, certified renewable forests.
