Everyone uses post-it notes in today's world. But the 2 x 2 are too little except to mark pages because there is not enough space to write anything of real value. The 3 x 3 give you just enough space to add notes or reminders of what needs to be done. Leave the stickies for everyone: On the refrigerator for your family. Leave them at the front or back door (or even bedroom doors or bathroom mirrors) so that family members see them coming or going. They don't mar any surface. And once the message has been delivered? They can be recycled; they don't need to end up in the "trash." Very useful!
I bought these on sale and was very pleased with this product. They work just as well as the "name brand" product and were probably half the price. I will definitely buy the Staples brand again.
