This is a high-quality violin chin rest made by Tempel Workshop, a long-established German fitting specialist, featuring titanium hardware. It achieves a light weight of 47g (actual measurement) through the combination of high-quality ebony and titanium hardware. Furthermore, titanium hardware is said to be beneficial for those with metal allergies. It fits standard 4/4 size violins. This item was purchased as a spare but has never been used and has been stored at home, so it is new and unused. Shipping will be on days other than Tuesdays and Thursdays.
