So many uses already mentioned here, plus....bills that are to be paid, clip them together so they stay in one place until I get to them. Coupons I've just clipped from the newspaper until I can get them in my coupon folder. Pages which for any reason need to be held together but not necessarily stapled. Letters sitting at the door waiting to be mailed, no more falling in back of the little table I have there. When using a cookbook, clip the page you're using and even if the book closes, which it will, it's easy to find. I have the jumbo size pack of small red ones and also have the large green ones. Best invention in years IMO.
