Wittner Composite 3/4 Violin Chinrest - Side Mount - Hypoallergenic

Ergonomically designed and allergy tested, this elegant chinrest is comfortable and high quality. Cup & fittings are made of an ebony-look composite; no metal touches the skin. Fittings are designed for easy & secure attachment to your violin (adjusting tool is included). Eliminates the allergic reaction common with many other chinrests. While Wittner sizes these 4/4 or 3/4 both will fit either a 3/4 or 4/4 violin. The only difference is in the cup size. The ovaloid cup measures ~4.25" x 2.25" on the 4/4, and 4" x 2" on the 3/4. This is a very comfortable chinrest.
