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. If you are searching for the original MP-110 cartridge, that can be found here.
