You can buy AUR packages in various amounts to suit your needs. Available packages are listed below and any purchased AUR will appear as a number of Aurum Tokens in your redeeming system.
Aurum (AUR) is a virtual currency that can be used in EVE to purchase items from the Noble Exchange. These items include a range of exclusive apparel that can be worn by your capsuleer or traded to others for ISK on the in-game market. Aurum can be acquired by converting PLEX into AUR, or by purchasing and converting Aurum Tokens.
AUR appears as a separate balance item in your character's in-game wallet and cannot be transferred from one character's wallet to another character, even if those characters reside on the same account.
When you purchase an AUR package, a number of Aurum Tokens amounting to the value in AUR of the package you purchased will be placed in your in-game redeeming system. These will appear when you next log in to the game and can be redeemed to your character's in-game location.
Aurum Tokens are in-game items and as such can be moved and traded like any other in-game item. Your character can add the value of each token to your in-game wallet by right-clicking each Aurum Token and selecting "Redeem for AUR". After this step is taken the AUR is non-transferable.
