This is a high-quality violin chin rest made by Tempel Workshop, a long-established German fitting specialist, using titanium fittings. The rare boxwood (Japanese box tree) is very light, and combined with the titanium fittings, it achieves an ultra-lightweight of 36g (actual measurement). Also, I hear that titanium fittings are beneficial for people with metal allergies. It fits a standard 4/4 size violin. 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.
