- You can write directly on the sheet: only the upper and lower edges of the sheet are covered; the holder is non-reflective, keeping the page clear and reducing eye fatigue during playing. - Robust construction: the holder is made of plastic, providing a sturdy, waterproof and tear-resistant build. It resists deformation and helps protect and organize important music sheets or other paper documents. - Easy use and viewing: features a simple USB port and right angle connection. The hollow design makes inserting and removing the file easy. Double springs allow the holder to unfold 180 degrees and lie flat on a piano music stand for a comfortable viewing angle. - Use scenarios: - Home practice on a piano or keyboard, with clear visibility and protected sheets. - Classroom or lessons, where sheets can be easily inserted, viewed, and kept organized. - Transport or performance, where important music sheets are protected and readily accessible on the stand.
