Unsullied leather items

As others have mentioned, Unsullied tokens (here is a quick list) are randomly generated and have been introduced to help players gear up their secondary characters.
Being account-bound items, they are not subject to the usual restrictions and can be mailed to any character located on the account (regardless of the recipient's realm and faction) by typing CharacterName@RealmName or CharacterName-RealmName in the "To:" field of the mailbox interface.
Once a token is redeemed, a soulbound item appropriate for the character's loot specialization is created.
Unneeded tokens can be sold to NPCs.
Have fun!
