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!"
