World's Greatest Magic - Ring Flight (DVD)
Though conjuring effects with finger rings have been part of the conjuring literature for quite some time, it was British magician/mentalist Al Koran who first conceived of the notion of a borrowed finger ring vanishing and reappearing on one of the hooks of a key case. Ever since, this effect has been a staple of magician's repertoires and dealer catalogs everywhere.
