A Professional Band Folder that holds a lot of sheet music. These professional band folders have extra large accordion pockets to hold loads of charts. The pockets are 1⅜” deep for almost 3″ of music, compared to the Classroom Band Folder’s ⅜” deep pockets. The Pro Band and Classroom Band folders are made with the same materials, and to the same quality. The only difference is that the Pro Band has extra deep pockets. If you don’t need to carry a three inch stack of charts with you, then you might like the Classroom Band folder better. Also has reinforced metal corners, a pencil pocket. Folders are 14″ high and 13″ wide (when closed, of course).
