These are so realistic!  They have varied "age and wear" looks to them.  They have a strong little magnetic closure, so you could stand them up without worry of the things inside falling out.  They're each a separate piece, not very big, but you can hide a good bit in them or store extras of small office supplies in them.  Good size for passport, cash, flash drives you don't want to lose, photos....just endless possibilities!  You'll always know where to find those certain items and they'll blend in with other books or can stand alone as well.  Nice way to cut down on things that clutter up a desk or nightstand!
