.3 X .7 mil bi radial moving magnet phono cartridge.  Universal, meaning it will work with a newer model turntable that requires a 'P-mount' cartridge or an older style 1/2" mount turntable where you need to connect the 4 cartridge wires and use small bolts to fasten it to the head-shell.  I comes with the mounting adapter and the bolts to do this.  This is brand new and never been used.

Thanks for looking.
