This cigar holder holds one robusto (most common) size cigar. 

Considering how fragile cigars can be, this tube is a great way to protect it in transit, whilst keeping it dark, and sealed with the slot for an O-ring. The tube isn't just for cigars, it will fit a giant joint, a sausage, a tightly rolled sock, or whatever you could possibly need to store securely. 

It has a knurled lid making it easy to tighten and loosen, and a clip on it so you can attach it to a bag. 

Anyway enjoy it, and there's a smaller one on my page for joints / cigarettes
