Behold, the coolest thing you can put on your door since that Kelli Kapowski/Michale Jordan dual poster combo you had there in 1992. It’s an enormous, high quality decal of Han Solo in carbonite, a geek must-have for the not-low price of $140. But can you put a price on awesomeness? Apparently so, and it’s $140.
The effect works best with no actual knob, as seen here, but if you like, actually want your room secure I suppose you can work around it.
What else was carbonite used for in Star Wars? I never heard about it other than when it was being used to freeze people, but that can’t be its household use.
