Le Boy So Black and So Beautiful plus 1 [emoji7]

This might be the most beautiful black grained Boy I've ever seen. Is that shiny ruthenium hardware? Just stunning.

Question: Is this the grained lambskin (gulp), or caviar (grained calfskin)? I'm seriously tempted to try to hunt the same one down, maybe in Small though.

I am not sure if it's caviar or grained lamb. It feels like caviar to me.
