A couple of tiny fleabites on each decanter, but hardly worth mentioning. One stopper is shorter most likely due to a professional repair - see photos. One stopper sits lower in one of the decanters, because the throat of one decanter is wider.. The decanters (without stoppers) are the same height, but with stoppers one is slightly taller due to the repaired stopper and wider throat...
