20 sheets display up to 40 pages of larger sized original music: 229mm X 305mm (9 inch X 12 inch).
The Rondofile Plus 20 (20 sheets, black cover) is a specialised folder with larger than A4 sized Rondofile Sheets - 229mm x 305mm or 9 inch x 12 inch. The aim of this folder is to accommodate and fit the larger sized (American and Canadian) Orchestral and Band music scores and charts. Since it is slightly larger than A4, it can also accommodate A4 music sheets comfortably and snugly, which gives this folder an additional extra benefit.
Australian owned and patented, Rondofile was designed with inputs from orchestral musicians. The open front tab allows you direct access to the majority of the page where you can write on it. 20 pages - 40 sides.
