Blockhead: The Life of Fibonacci -- Joseph D'Agnese, HardcoverAs a young boy in medieval Italy, Leonardo Fibonacci thought about numbers day and night. He was such a daydreamer that people called him a blockhead. When Leonardo grew up and traveled the world, he was inspired by the numbers used in different countries. Then he realized that many things in nature, from the number of petals on a flower to the spiral of a nautilus shell, seem to follow a certain pattern. The boy who was once teased for being a

Defective Item
Color: Black, Color: Black
The door broke off immediately out of the package and the screws are stripped so they can’t be tightened into place. I might superglue it because I don’t want to go through the hassle of returning it and it’s the only way they’d offer even a partial refund for a defective product when I asked.

Strong well made but ..
Color: Gold
Coring tool broke as soon as I tried to loosen the top. As far as a tube goes it is great. Seals tight, solid Aluminum throughout. You could throw this off a tall building and it would be fine afterwards.

I love this thing!
I can't overstate how much I love this thing! As someone who enjoys a good cigar on the go, I've tried various single cigar cases, but this one is in a league of its own. First, the build quality is outstanding. The aluminum alloy feels incredibly solid and durable in your hand. It's clear this was made to last. I have no doubt that my cigar is perfectly protected from being crushed or damaged when it's in this thing. The convenience factor is a 10/10. It’s sleek, compact, and makes carrying a single cigar effortless.
But it's the brilliant integration of accessories that, for me, truly sets it apart. Having a sharp, reliable punch built right in is fantastic. The built-in hygrometer gives me total peace of mind that my cigar is staying perfectly fresh, and the clever design that allows the top to double as a cigar holder is just plain genius. This tube is the perfect, all-in-one solution for any cigar aficionado who travels or simply likes to be prepared. I'd recommend it to anyone without a moment's hesitation. Five stars all the way!
