Ferry Manik-Manik is Balinese beads guru. There are all kind of modern myphological stories about him :). Did you by chance meet Beny? He owns a shop in Legian street. He has a collection of old beads as well.

I have some beads from you collection and I also have different. They make a lot with golden foil now and small striped and mosaic beads. I left Beny a book on islamic and venetian beads and when I came back 6 months later they alrady had a new collection :))
