Is it leather or pleather?
I’d say sniff one. The last time I checked pleather didn’t yet smell like leather. Ditto what Wolfie said also. I have a very expensive length of apparel wear quality leather sitting in my closet right now, and it has a stamped grain. On this piece, the process used to create the suppleness of the leather removed the grain, and some people like grainy leather (I suppose to make it “look” like leather), so they stamp it. I’d imagine that quite a bit of actual leather grain that you see in products is stamped, as what I recall of watching my grandfather tan skins, it can be hard to keep the original grain during processing on some leather.
