I've been using canary yellow narrow ruled three hole punched pads for years. They stand out in my job notebooks as holders of handwritten notes minutes or sketches and make it easier to find in a file of white copy paper. Very useful!
This notepad is high quality note paper. Because it is narrow-ruled as compared with wide-ruled or college-ruled you can fit more text per page. Also the cardboard backing and the perforated top make it exceptionally easy to use.
