Humidor in fragrance storage?

Recently bought a humidor; trying to figure out where to put it. The most convenient spot is in a bookcase that currently houses my perfume collection. Cigars and fragrance both should be kept out of light and heat, and it is in a cool, dark spot, plus it has a lock on it so the kids can’t get in. If there are any cigar smokers in the community, do you know if a humidor might leak any moisture that would affect the fragrances? I bought a decent one, it’s the Case Elegance/Klaro Renzo so hopefully the seal is pretty airtight and doesn’t let anything in or out.
