Ceramic mug, approximately 12oz. We all know Army Men are the toughest, most rugged players in the game. So it's only appropriate that you let the Army handle your coffee. Your mornings are rough, straining and usually bumpy. You may not be doing bootcamp training with a plastic base holding your feet together but it sure feels like it. This awesome mug is easy to hold and let's everyone know you mean business. Hand washing recommended.
