I use these to tag all sorts of things at work mostly and even at home. Reminder notes on calendar. I end up moving them from week to week when the tasks get pushed out and they stick again and again. They are great for short notes on reports I distribute when I don't want to write on the rpt itself.
Bought these for a school teacher that zips through post-its. They were on sale and a great deal at that price. They are really small but enough space to write the date and one word which is the main purpose in this case. I don't think they would have been my prime choice if I had not gotten a great deal on them. They would be best used to tab mark a book or when VERY little description is needed. With 1200 sheets I hope this lasts even her a couple of months.
