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.

keep your cigar safe

not too sure about the hygrometer, but really nice looking, great quality, and what an amazing hole puncher it brings.

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.
