That special dilemma of buying old stuff that's never been opened. Should I open them up and display the ships on my shelf? Or leave them in the box where they can't be examined and enjoyed up close?
Beat me up over it but unless I have a good reason to open MIB stuff I keep it new in the box. It's nice to have to look at, and unless you're actually going to play with them.
For me personally, I like being able to look at them from every angle. My favorite ship of this lot of Micro Machines is the old Klingon Battlecruiser. That's the one that got me looking in the first place.
