This is a rather special item 'Ayin Ha'ra' translates from Hebrew as 'Evil Eye', it brings the wearer protection from evil by reflecting any directed at it in the shiny glass. These are very popular charms in Turkey and you wouldn't be able to go many places in Turkey without seeing these. Would make a perfect center piece to a necklace or just used as a charm hung on the wall, keyring, etc.
