As the title says I am curious what makes the leather shiny on several of my strops, I have a Spanish Bridle that has a high glassy reflexion just like my Kanayma 70 but my oil tanned ones look kinda flat then my Fast Bridle has what I would call a satin sheen, the Spanish Bridle did not start out this way , the only thing I have done to it was add a small amount of Fromm Strop treatment to it after it looked like needing some moisture
