Cuir Pleine Fleur, or Full Grain Leather, opens nicely, and a soft leather is evident on top. Then it changes, quite dramatically, into something fetid.
My first thought: Bird cage, needs cleaning. My second: City zoo, elephant pen. My third: State fair, pig barn. My fourth: Open, untreated animal wound.
The birch is beautiful - the best I've yet experienced - and the earthy, woody dry down is very wearable for me. But the farm experience ... it borders on repulsive and it's a little much.
Thank you @CatBiscuit for endowing me with a sample of this beauty. I'll use it on one fine day to piss off my co-workers, or I'll wear it in Vegas to make my way through a crowd. Either way, it'll go to good use. ;)
