The size is perfect. It fits in the Day Planner and allows me to take notes or jot down info I need to keep track of. I use it for reminders to-do's notes---it's just really handy.
I love that they are in different colors. i use one for each subject needed and can grab it at a glance. The paper is white and strong and the price is perfect. i buy lots every year and use them at the office at home and for giving to someone who needs paper in a pinch at a meeting. Affordable enough to keep them stocked in my closet.
