Otello is an opera in four acts by Giuseppe Verdi, based on Shakespeare's play Othello. It was Verdi's penultimate opera, performed for the first time in 1887. While Othello is a tragedy, Otello pipes are quite the opposite, with happy dispositions and a confident stance. The "670 KS" is a half-bent Billiard in KS size, here rendered in a deep, dark rustication. Can be used with or without Savinelli 6mm balsa filters(10 included). Comes with 6mm to non filter adapter.
