The Stanton 500 Series replacement diamond stylus is designed for Stanton phono cartridges. It is a high-quality, translucent conical diamond stylus that fits various Stanton models, including the 500, 505, and 510. It is new, unused, and clean! I accidentally purchased it in the US and it didn't fit my turntable, but it is not defective. Please check the shape in the photos to confirm compatibility with your cartridge. Please confirm before purchasing.
