File folders used to be made from 14 point paper stock but in recent years standard file folders are being made from 11 point stock. If you don't plan to use the folder very often these folders are okay but they won't stand up to frequent use. Staples does have the heavier folders but they cost about four times as much. However I prefer them to these because they are more substantial. I use these folders for infrequently used files. If you won't be accessing the files very often these folders are a good choice because of their economical cost but if you use the folders regularly you may be better off buying their 14 point stock folders.
