Work very well!!! I would recommend to anybody. They are heavy duty and are not bright enough to get lost on your desk. These are folders that can be reused for along time. Eventually it buckles a bit from wear and tear but it lasts much longer than most other folders would. Only con I can think of is that you have to be careful what sort of stick tabs you use because they can be prone to peeling off.
File Folders are a way of life: These come in manila or colors and are great to cut up for envelope mailing stuffers for item like photos that you do not want creased or bent.
