Gentlement, could you point me in the right direction as to where to purchase 1) corozo buttons (@EliodA?) and 2) (dark) brown buttons?
I think I'll purchase both and see what looks best with my newly accquired navy blazer.
Corozo can be found on Amazon, Ebay or Etsy. Many sellers are in the US though and don't do international shipping. If you're more adventurous (and patient) you can even try Alibaba or Aliexpress.
