So I recently decided to start looking for a humidor but couldn't find one that I really liked the look of. I'm a big fan of modern and minimalist looks and I started thinking of if making a cigar humidor out of concrete would be something feasible. I already have experience working with concrete, and I know that I would need to line the inside with Spanish cedar and i'd only be looking to hold 50ish cigars. Does anyone know for sure if this would work and hold the humidity? I think it would work but I wanted other people's opinions before jumping into this. The picture I attached may give you an idea of the look and aesthetic .
