modification of the comment after treating the bag with superfine cream Saphir:
The front of the bag is thick good quality leather is even more beautiful, but the back and the flap are not more "brilliant" and we always see that the leather is not good at these places.
I sought advice from my shoemaker (by buying the sapphire cream) he thinks it is not the full grain leather, but the split leather (leather cut into the thickness to obtain several pieces of leather) which explains that the leather is thinner and fragile in some places.
I'm a little disappointed with my purchase, I think we can get a good quality bag if the leather imitation is good ... otherwise .... unfortunate is the lottery.
I would buy perhaps "Marius Paul" if I cross shop to check product quality, but not on the Web (though I was very happy with my first purchase: Pressure kit + purse very good quality).
I took pictures, unpacking and after treatment but I have not found how to insert my comment.
