Season Well and It Still Might Not Work
Humidor was seasoned, per the instructions (and more). Yet it will not keep humidity above 60%. It appears the seal/gap is to wide because of the hinge placement. They need to be recessed a bit to create a tighter seal. I have 15 cigars in this box, plus a Boveda 69% 60gram package. Max humidity is 60%.

Impressive Gift
Size: L ( Fits 25-50 Cigars), Size: L ( Fits 25-50 Cigars)
We had another humidor that didn’t have a humidity gauge. Found out that even in high humidity Houston we were not storing our cigars at a high enough humidity. This is a very well-made, sturdy humidor. (Our old one pales in comparison and I thought it was nice!) You open it up and the smell often the wood is just lovely. We often buy Cubans while abroad, and go a long time in between using them. We are not going to take a chance with them now. We will only use this. Perfect for a gift for your cigar aficionado. I think this box is a good value for the money and you will preserve your cigars much better with a digital readout.

That the unit is not air tight as stated!
Size: L ( Fits 25-50 Cigars)
It is stated that it has tongue and groove lip and will easily pass the dollar bill test, but it will not!!
