FITS 1/8 to 1/2 SIZE VIOLINS. The “Petite Original” violin viola shoulder has a taller hook with a steep angled cut-away and a very thin base that’s flat and straight without any curvature, which is great for players and children with a relatively short neck. Since the base, which goes over the shoulder is flat, this model is the most universal. One “PSR Elastic Band” and one “PSR Magic Strip” are currently included. Try the “STRAIGHT” or “ANGLED” placements for your preferred comfort, made of resilient contoured ergonomically designed foam with great memory to bounce back to its original shape. Our PATENT NUMBER 7,262,352 design curve assists proper placement for your shoulder rest.
