I went to the NM store and wanted to get a black city bag. But it seems everyone is different, some are smooth and shiny and some are veiny and crinkly. Even the black color is different. I asked the sales why they look so different, she just said because every piece of leather is different, is that true? The one I like which is veiny and crinkly and not a bright black color, she told me that is called "lead" color not black. Is there a color like this at all? Or it is just black? Inside the bag, the label says N 2076 U, what does 2076 mean?
