Rondofile has created this unique folder is to make annotation on music quicker and easier for teachers, musicians and instrumentalists. As musicians, we all know how fiddly and time-consuming it is with the ordinary plastic pocket display folders whenever we want to annotate on the music sheet. Rondofile has solved this problem with its specially designed plastic sleeve which incorporates side tabs to fasten the paper down. This leaves the majority of the music sheet exposed as a workable area for direct annotations.
