Review on Copper Flask Closure: Exquisite Vintage Craftsmanship for Superior Quality by Mark Ponnusamy

This bottle has a very cool design, the only downside is that it's covered in copper and sometimes it can leak a little because it's just a cork. It works best when you can carry it upright in your pocket or purse. I still think it's really cool, you just have to be realistic in your expectations. I wouldn't take this campsite for a week but I would stuff it completely in my coat pocket.
