I am not sure, but I think this might be the best $10 I have spent in quite some time. The Belt Buckle Flask is exactly what you imagine. It is a belt buckle, which is nice because it holds my pants up. And bonus, it is a 3-ounce stainless steel flask for holding some of my favorite liquids. At first glance it was a tad bigger than I expected, but if it were any smaller it would be useless. In other words, it is just right. I recommend getting the tiny funnel as well, makes filling the belt buckle flask much easier.
