The price is ok if you consider that only the genuine GPF buckle like this go for 500 euros
I personally dont have that amount money and I believe other straps are by far more interesting BUT the price is OK..
The vintage Pams are now 50.000USD and they literally most of them don't worth even the 1/100 of that price.
It's the HISTORY, RARITY, and exclusivity that makes the price.
