ZYX DIAMOND-X TOP TIER Cartridge, almost no use

Selling this one for our Customer, It has almost no use, sat on a turntable with three arms and received very little action as the owner used the other cartridges.  It was replaced by a Ortofon MC Anna last year and have sat in the box since then. Just this week we installed 2 new arms on the customer table and he asked me to move this one along with the two arms we took off so look at my other listings for these.
I've taken details pictures via a USB Microscope so you can see the SHARP Straight Stylus and Cantilever
