General Slot Car Storage?

I wasn't sure where to post this question.

What do people use for storing slot cars in general the ones which are not in use or on display?

Personally, due to space restrictions the majority of cars are stuck in cardboard boxes and needless to say, it looks naff. Are there any suitable alternatives which will keep cars safe from damp (in case of attic storage) etc?

Preferably the cheaper the better!

Okay admittedly not the most enthralling subject, however any ideas or recommendations would as always, be much appreciated.
