We have been using these folders for quite some time. They hold up well and do the job but if you like to alternate the tabs for filing purposes like we do be prepared for to end up with 2 to 4 in each box that are the same tab. The company could do a little better job of a more even disbursement so that there is less waste. I'm sure we are not the only ones to notice this. We have an accumulation currently of middle and right tab folders but no left tab folders to use the excess. However for the quality the price is worth it. We have used others that are not heavyweight and they are the pits to file with.
