Very rare! Dr. Marten's Langston boots in Petrol Oil Slick color. It was a bit dark today so going to get some lighter photos to show the irridescence. Close-up you will see a tiny cut/puncture on one and some small cracking at the toe crease. IRL hard to tell, but see a lot when zooming in in the light. Clearly, a leather wipe will leave residue/fragments when you wipe them down :) Lesson learned LOL.
