Claiming the t1 box on an alt <80

in brief words just to be sure:
claiming the box equip t1/necklace/cloak/weapon/saga vanity must be done before 90 days
once claimed the box/accessories/vanity even if unopened stays forever in inventory (in my case in a brand new lvl 50 that will be 80 in a slow way)
is that right?

Sounds right to me.
