^In addition, if it's a Matte Nilo Croc or Mississippi Gator, it's understood why it's a Mou. Like how a Matte Croc Lindy or Jacket has the Mou effect. Like-wise, SO Kelly and Jypsiere in Matte Gator. This is what a Hermes craftsmen told me before. Moreover, if the Matte Croc Birkin has a toile lining.
Since we're in the topic of Crocodiles, a recent of article of a croc skin supply to Hermes cost about $1000 only. Of course, this don't represent the whole of Hermes since it has its own farm. Dad to bag designer,
