Very Pleased

Holds quite a bit of cigars. Air tight. The Bovida packets seem to last longer. Well made box. Very, very pleased. Highly recommend.

A classy gift humidor that feels more premium than its price.
Size: L ( Fits 25-50 Cigars)
I’m no cigar aficionado, but this humidor gives off a premium vibe. The cedar lining, glass top, and included hygrometer make it look and function just like other consumer-grade or gift humidors I’ve owned in the past. It maintains the right environment for storage, and the build quality feels solid for the price point. As a gift, it looks impressive and works as expected—definitely a worthwhile buy without needing to break the bank.

Solid cigar box with premium touches
Size: L ( Fits 25-50 Cigars)
This humidor ended up being way nicer than I expected for the price. The digital hygrometer is a great touch and super easy to read without opening it. The glass top feels sturdy and gives it a clean sharp look on the desk. The cedar lining smells amazing right out the box and really helps hold the humidity steady. I got the large one and it easily fits a good mix of sizes. Gave this as a gift to my uncle and he was honestly blown away by the quality. The value for the quality of this box is phenomenal. I love the digital monitor that gives you the humidity percentage, and having a "refillable" part that you use to humidify was such a big plus for me. Super easy to maintain, and super easy to glance at and make sure it is at the correct humidity. I love not having to wonder if I need to add more humidity and fear of ruining my collection! Must have for anyone looking for a humidifying box.
