This is not an Ortofon 2M Cartridge, but rather the replacement stylus which you buy to save a little money (and have that much less plastic floating in our oceans).
You need to already own an Ortofon 2M Blue cartridge to use this. To install, slide the old stylus from your existing cartridge, and replace with this.
