I purchased this about a month ago and it's already falling apart. Definitely go with the standard looking brown file, you'll get a better quality for your money.
We use this file in a busy medical office to sort lab reports to be filed in patient charts. This file started falling apart after 1 week. This file was not designed for heavy use.
We receive LARGE quantities of paperwork through the mail on a daily basis. We use sorters to pre-sort them for alphabetical filing later. I was under the impression these were mylar accordian files; like the mylar files, they're not - they're just pressed paper like the regular brown accordian files. I could've saved some money and purchased the regular brown accordian files. I won't be recommending these to anyone else.
