A very Good Composition.
I will compare it in my review with Tuscan Leather by Tom Ford and Parfum de Marleys - Godolphin.
I tried it side by side one week with Tuscan Leather and Godolphin as they are all really close in composition!
What I can Say is that Tuscan Leather is more smokey and les raspberry while Black Saffron is less smokey and more raspberry sweet. A femininer Version of Tuscan Leather.
I dont get Leather at Byredos Scent. It is very sweet an more fresh.
Here some specs(max 4 Stars for strengh):
+Tuscan Leather =
+Black Saffron =
Vetiver / Lemon/ Juniper mix
creamy/ flowers/ musk
In total it last 4 to 6 hours. Less then Tom Ford and same as Godolphin I would say.
Try it yourself! I prefer Godolphin still. Will update maybe in future my experience. Memos - Italian Leather soon enters the ring! It is kinda close too.
