Named as an homage to the jewelry tradeshows in Tucson we attended every year, our Arizona flat leather is made of a sueded top-grain leather wrapped around a cotton core for stability. The 3mm size is solid suede and does not have a cotton core. Our Arizona leather it has become a popular options for designers searching for a jewelry leather with soft sueded texture. It makes a wonderful contrast to our smooth sleek plain leather and can be paired with all of our regular flat leather components.
