I got this very nice metal display cabinet with doors a couple weeks ago . Recently , I just decided to renovate the top to hold some of my nendoroids . Ive been a little afraid of it for some reason .. And I that's mostly because it's metal and not wood . Everything in my room is wooden shelves , so this metal shelf is new to me . That begs my question - Is it safe to store them in here ??

For some reason the thought is eating my mind up that they'll somehow magically get stained blue or become discoloured , and I suppose I just need the thought to be shaken off by other nendoroid collectors and their wide ranged experience with displaying and store nendoroids outside of their boxes !!
