There is a small village, Kokofrom just outside Kumasi, Ghana where there are Artisans who make lost wax brass beads in the same way as their ancestors. This copper spacer was made for Funky Frog. The copper spacer is about 3 mm.  The artisans use whatever scrap metal they can get their hands on from old taps to pipes to .. but they call it 'brass'. $5 /20 heishi
