This is a tumbler I won from a Premium Malt's promotion. It's made of copper. I was a fan at the time, so I worked hard to get it. I've never used it because I didn't want to, and I've been storing it, but due to poor storage conditions and aging, there are peeling, noticeable stains, and dirt. It's definitely not in good condition, so it might be suitable for display purposes. I washed it thoroughly before listing it. Please check the photos for the condition before purchasing.
