When you are practicing or playing, the sheet music folder is your perfect choice. It makes reading music easier and brings more convenience to the performer. The sheet music folder can be expanded to hold 4 pages at the same time, allowing you to complete performances without turning pages, which helps avoid interruptions during play. There is no barrier between the inner pages, making it easy to insert or remove music sheets, or write directly in the folder without taking out the score. When performing on stage, the design helps reduce light reflection, making the sheet music easier to read and helping to relieve eye fatigue. The cover is made of frosted PP material, offering waterproof and drop-resistant protection for long-term document use. The folder features a metal double-ring spiral binding with accurate opening positioning, which is not easy to loosen, allowing sheets to lay flat up to 180 degrees. It has a 4-sided PP hard cover that provides strong support, keeping the sheet music stable even without an external music stand. The corners are designed with a semicircular shape to prevent hand scratches, and the inner pages remain stable, reducing the chance of sheets falling out. The folder can hold up to 40 sheets of music at once, offering more capacity than standard sheet holders. It is suitable for musicians of any instrument and for various occasions, serving as a reliable accessory for performers. This sheet music folder also functions as a multifunctional file organizer, capable of storing documents and files beyond just music scores.
