Can I put mog station items in it? How about exclusive promo items like the maid outfit, eastern journey outfit, or (ugh) the ifrit/titan masks? Will we lose them permanently?

Any ideas? I've not even taken the eastern journey items out of the mail because I can't put them in the armoire and I don't want to waste inventory slots. Still a little sore that they refuse to let us store these exclusive items in the armoire.
