We have a refrigerated display case for wraps and salads at my movie theatre. For the past couple months, I've left comic books in there as a backdrop- nothing worth much, mostly 90s X-Men and Thor. But now I'm considering putting some TFs in there on display. How much damage might occur to a typical movie-type TF? I'm not planning on putting any metal, die-cast ones in there, but about 6-10 toys.
