I tried to transfer "Mannequin Hands" from one character on my account to another. "Mannequin Hands" is greyed out.

I checked the latest forum notice about Undeliverable items at--

http://forum.square-enix.com/ffxi/threads/14591-Undeliverable-Same-Account-Ex-Items

and using the search function in the browser, was unable to find any item with the word "Mannequin" as being Undeliverable.

Either the forum list is missing the "Mannequin" items or they have been improperly flagged as being Undeliverable in the game
