Hi! So the custom Mattuo strap extensions for my City just got to me and they're pretty great - not quite a 100% match, but then my bag's a Metallic Edge in chèvre with the light gold h/w colour which is probably harder to match. You'd never notice any difference in leather or h/w colour at all unless you looked really closely. I think they're going to make the bag much easier to carry. I recommend Mattuo!
