These are great cast metal, small, simple conch shell charms in the bronze patina finish. They would be fab on necklaces, bracelets and earrings. The hole at the top is 2.5 mm.
Cast metal beads, made in Mykonos Greece. Mykonos Castings start with a lead-free base metal, but are then coated with copper and finished (in the same way their Metalized Ceramics are finished) with fine metals (pure copper, fine silver and 24k gold).
