This is a page clip for holding sheet music open for accompaniment. In the past, when I have tried to play from song or hymn books, it was difficult to keep the book open. This is larger than the average music page holder at 244.5 mm x 83.4 mm and 4.5 mm deep. The base is 2.5 mm deep with the black piano notes, text ("Music", "Bound"), and initials extruded up to 2.0 mm. There are filets and chamfers throughout. Ideally, it would best created in a clear plastic.
