The Choir RingBinder is ideal for musicians, singers, and directors who mostly use hole-punched sheet music. The Choir RingBinder features a comfortable hand strap that allows for one-handed use. It also has large solid rings that lock, even when opened flat for use on a piano, organ, or podium. Made with a solid one-piece board construction for great durability, yet "Oh, wow!" light.
