does the job!
I bought the DXXULL 4-in-1 Cigar Tube as a gift for my husband, and overall, it’s been a solid choice. He travels often and enjoys cigars, so this compact, all-in-one tube really suits his lifestyle. The aluminum alloy feels sturdy and well-made, and the built-in cigar punch, hygrometer, and holder add a nice touch of convenience. It’s sleek and functional—he’s used it several times already without any issues. While I do think it’s a bit overpriced for its size, the quality and thoughtful design make up for it. If you’re looking for a practical, stylish gift for a cigar lover, this tube does the job well.

won't fit Churchill length or 60-ring diameter cigars
Color: Gold, Color: Gold
This is a good-looking device, solidly built, with a handy twist-out punch in the top and a humidity gauge in the bottom. The hygrometer is pointless, because there is no way to add anything to actually maintain the humidity, and since I would only use it to bring a cigar to a gathering, it really does not need to maintain that humidity for the 20-minute drive.
What really bugs me about this is the actual useable size. I primarily smoke 2 types of cigars, 54-ring Churchills (which are 7") and 60-ring Gorditos (which are 6"). Although the overall length of this is 8 1/4", the listing never mentions the interior space, which seems to be just under 6 1/2" when closed. My Montecristo sticks out about 1/4" when I insert it, and that does not take into account the 1/4" that the top pushes into when closed (that silver-colored area is solid), thus less than 6 1/2" useable length. Even out of the wrapper, my 60-ring Gorditos sticks when I try to push it in, so I'd have to take off the band(s) to force it in, and it would not slide out very easily, so I would mangle the cigar trying to get it out. So, this can hold a cigar that is 6" or less and maybe 54-ring without the wrapper. Anything else, and you would have to force it in and force it out. So, this unit, while very good looking and well built, does not work for my cigar needs.

My boyfriend couldn't be happier
Color: Red
He lost his original nubber and has been a cigar smoker for 20 + years. He said it is the best thing since it has a nubber, cutter, punch and is very well built. He works in cigar marketing and says it's worth the buy

10 /10
Color: Gray, Color: Gray
"I was impressed from the start—this cutter arrived quickly and the packaging was beautiful. The moment I held it, I noticed the weight—it feels solid and well-crafted. The engraved details are stunning. The mechanism opens smoothly, and when I made my first cut, it was flawless—no damage to the cigar at all. This is easily a 10/10 product for me!"
