Books can be used to hide all sorts of things. I've seen hollowed out books used to keep jewelry safe but this vivid box from Assouline is meant to house your cigars. Don't look for this one to rest discreetly in your shelves. The Assouline library humidor measures 13.7 x 13.7 x 13.7 in and is made of wood covered in black leather. The doors display the titles of Assouline publications (even one called "No Smoking") and the inside has a humidity gauge. It sells for $2,000.
