Means it's a fake then. Sorry. It should be Riri or Lampo. Some of the older ones have other brands. Also just saying Riri or Lampo isn't enough, because they fake those too. You have to know what to look for.Do all prada zippers have the manufacturer name...Riri or Lampo on the back? I just got one from re-sale boutique in L A that has no name on the back of the zipper...also there is no little tag in the zipper compartment with a number on it.
