How do i get the title and the special Decal if I have the vehicles

So my problems is where do i get the “Unique decal: Chinese snow globe” and the Unique title: The fireworks expert when i already own the two vehicles (t62 545 and F-5) in which case i cannot get the decal because i didn’t buy the winter pack. for the other ones i didn’t but the helis so I can just buy the pack and i got the titles.
