They are great with the hanging ability to keep them in place. Easy to find unlike manilla envelopes that slide down and get crushed. Needs to hold more be wider. They only hold a certain amount until you have to get something else to put them in.
These folders are used for filing. I use one color for business correspondence another for small claims court case another for federal court case and another for appeals filings and supporting material. Having different colors is very helpful that way. Although they're "generic" the quality is quite good. The product is sturdy and will hold up to long-term use.
