Okay...I'll be the one to say what we are all thinking....
First off, awesome job. You created something using creativity and ingenuity out of your passion for cigars, and that is very cool.
What I am about to say is intended to be helpful, and not to tear down your creation......You didn't line and seal the inside with Spanish cedar, and this is a problem for two reasons.
Cedar promotes and assists proper aging of cigars. Even if you aren't aging them, and (even if all of your cigars are stored in cedar boxes) the cedar is consistent once it is saturated with humidity and is the best wood to use for this purpose.
Second, cedar won't mildew or warp with the constant humidity that the inside of a humi withstands. The wood used to make that cabinet may warp over time, causing leaks that are difficult to find, not to mention compromising the structural integrity of the entire humi.
Also...(sorry!) you may not be able to smell any of the potentially harmful glue, sealants, lacquer, or any other agents that are present in that cabinet...But they could easily destroy your stogies over time.
Again...Just trying to be helpful, Bro.
