My GF bought me a CAO Black 100 Count humi for V.D. Before i went to season it I noticed what seemed like a little bit of creaking from the wood everytime i closed the lid. So my next move was to do a light test to check if it still sealed properly, as the lid seemed as if it had warped. I took a flashlight and set it inside the humi so that it was shooting its beam towards the side where it seemed to be warped. I can notice some light coming through. Before I go and send this back for a new one, is there anyway it can be quick fixed, or is a minimal amount of light even a big problem?
