"Cazal, the brand name, was created as a combination of the first letters of its designer’s name: Cari Zalloni. In the 80s he created his own style of glasses which in the meantime has come to represent extravagance and quality at the highest level. 25 years ago he gained dubious fame in the USA when two people were killed over one of his popular models. The Cazal 607 is one of those precious models since it became a steady component of the American Hip-Hop scene in the 80s."
