Decolav Double-Walled Drop-In or Undermount Lavatory with Overflow

I ordered 2 of the same sinks at the same time for a dual vanity. The first one arrived 3 days before the second one and when the second one arrived it was a totally different sink. It was round and polished but the Decolav stamp was on 2 different sids, the overflow on one was 3 large holes and on the other it was 4 small holes. Also they were not the same size. Bottom line, the sinks had they been the same would have been beautiful but there product quality is not always the same.
