Ah, the good ol' Mayor. I know that these collectibles are worth more in the package, but if your only goal is to resell them someday, might as well just stuff them away a dark closet.
Models, figures and dolls are meant to be seen and played with, that's what I say. I have plenty, and they're unboxed and sitting on my shelves, so I can view and enjoy them. For example, I just got a new doll that I promptly unboxed to play with. Right, Hottie?
