Purchased wrong Attachement on Item Mall (Male Character, Attachement Female)

[Cocoon]

Is it possible to remove the Attachement out of my Inventory and add the Silk back?

The Attachement is called "Cursed Soul Accessory (F)".

My fault to say, didn't noticed there was only one Cursed Soul Accessory and that for Female.
Since my Character is Male ... it won't match.

Thanks ^_^
