Nagaoka NC-201 Ceramic Stereo Cartridge w/ Diamond + Sapphire Flip-Over Stylus. Originally the cartridge box was insulated with foam. Over time the foam started to deterioate so I completely removed the foam and replaced it with bubble wrap to ship it securely. The NC-201 has a .7mil diamond and 2.5mil sapphire flip-over stylus. The package was not sealed so I am selling this item as used to be safe. The screws/nuts/manual are not included.
