Herdim carbon fiber chin rest for violin. It is lightweight and made of high-strength carbon material, weighing 47g including the hardware. Fits a standard 4/4 size violin. It is said that lightening the chin rest improves the tone and resonance, but please understand that this is a matter of personal preference. The product was purchased as a spare and stored at home, so it is new and unused. Shipping will be on days other than Tuesdays and Thursdays.
