Ok... so there I was at NM again and I noticed that all the bags that weren't city bag didn't have the metal serial plate on them in the same place that I would expect it on the City. Do the day bags, twiggy and box bags not have these? If they do have them, where are they? Second question, I think I'm going to get one of the green bags for summer: Emerald Day Bag or Emerald Twiggy? I can't decide. Thanks!
