I wanted plain yellow post-it type stickies and I couldn't find plain colored Post-its in a reasonable quantity or price. Then I found these which were much more inexpensive than Post-its and in a reasonable quantity. I have a daily planner that doesn't provide a lot of room for "to-dos" so I take a short stack of these and keep them in the back of the planner and then I use one at a time as needed to write down my lengthy agendas. These worked great for my system!
