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!!

Great organizers!

Color: 12x6-3P-Black

These baskets are very useful. Junk drawers can be areal mess but we use these to bring some order. They are just the right height for the shallow kitchen cabinets.
