A "Grade A" Factory Second folder will have small flaws that don't allow it to pass quality control. It might relate to closed alignment, a scratch, a stitching issue or some issue with the cover material or pocket alignment but should not be visible to the audience at a choir concert, and saving 25% on these should be considered a very good value. 

The Choir RingBinder is the best music folder solution for choral singers, directors, or conductors who mainly use hole-punched sheet music. It's also compatible with magazine holders / octavo holders, which can fit into the rings and allow larger scores and sheet music that is not hole-punched, to be used at the same time, placed exactly where you want in your concert order. This version has large, 1.5" diameter rings.
