We take a look at how 10 brands make their most iconic items from start to finish. These include Dr. Martens' shoes, Catbird's engagement rings, L.L.Bean's sold-out duck boots, ColourPop's eyeliners, Dr. Bronner's castile soap bars, Fender guitars, and Nalgene water bottles. Each company has its own unique history, and we get a look behind the scenes at how the products are made.
