This is the Genuine Nagaoka JN-P110 needle for the Nagaoka MP series cartridge. The JN-P110 features Nagaoka's polished SUPER-fine elliptical diamond tip.
The elliptical tip enriches tone and detail by tracking the grooves better than its conical predecessor, the JN-P100. This is the original replacement stylus for the Nagaoka MP-110 cartridge.
