This produces a natural looking product that will have some natural marks, scars and other blemishes. In other words, it has not been processed to make the leather appear perfect, like something you would get in a department store. When you get your brand new undyed, vegetable-tanned leather goods, you are seeing its natural color. The hide is effectively naked and so will age and darken with the sun just like your own skin. Aging will develop a rich color and patina. Sun exposure, daily handling, water, and conditioning give natural vegetable tanned leather a rustic look over time.
