Was digging through some gear and found this: http://ffxi.allakhazam.com/db/item.html?fitem=10894 I think this should be classified as feet, not as neck. Of course there's a good chance that I'm mistaking it so if I am just ignore this.
On that note if you want to report further items, or add missing ones, or anything in general with FFXI database here you can use this forum or email the FFXI team at ffxiteam @ zam.com :)
