One more thought...When i looked at it from the side...i swear i can see through the hinges. So i went to the sites you suggested and i see they have the exact same one i have.....i am sure its the seal...i am watching the digital hygrometer in the plastic sac with the crystals and it has already bumped up 4 degress which it never did when it was actually in the humidor itself....Thanks for all your help with this matter.......
