that with the rattle I can only confirm: if you do something purely that is not made of paper, you should kick it a kind of "softer coat". The leaves I find not too thick - they are as it is such a thick book just heard! What is something that bothers me that not a single leaf on the safe is - once you open your book cover, can be seen immediately the vault. It would have been better if at least the first 2-3 pages, which are typical for a book that would have been possible. The first pages have a blah about Kopyright, editor, author, etc. can be and possibly even a chapter overview that matches the cover. That would certainly not cost so much more and it would have seemed more authentic! - An otherwise: one can not expect that the part is like a bomb-proof wall safe, than someone who thinks that, I can only shake my head!
