The binder includes an elongated dorsal part having a first longitudinally extending side and a second longitudinally extending side. A plurality of gaps or openings are spaced equidistantly along the perimeter between the first and second sides and a plurality of flexible fingers extend adjacent the gap opening, curved around to face the inside of the dorsal part perimeter adjacent the second side.
