I have a few questions for people who are probably more knowledgeable than myself. I already know all the stuff about avoiding heat, humidity and sun exposure but how about storing toys? Is there any rules I need to take into consideration?

I have too many toys in my collection and my place is super small so I have to rotate stuff out but some stuff i've left in boxes for years. Is that a problem? Should I just open them up every now and then or do they need to be removed entirely for prolonged periods of time?

Also, when storing toys in their original boxes does it really matter if they're upright, laid down on their back or sideways? I find sideways gives me more room in my setup or some lines but will storing them sideways cause warping or break them? Most my stuff is imports with full clam-shells if that makes any difference. Just wondering if these clam-shells have been designed with a certain orientation in mind or not. Thanks in advance.
