The Arturo Fuente Fuente Opus X is the first Dominican puro ever made, at a time when the fertile soils of the Dominican Republic were considered perfect for growing tobacco but not for growing wrapper tobacco. Arturo Fuente proved the cigar industry wrong when he introduced the Opus X, a cigar that quickly became the most sought after cigar in the world. The Forbidden X Heart of the Bull cigar is part of a special 100th Anniversary blend that is available only at the top Fuente retailers in the country. They can be distinguished from the regular Arturo Fuente Fuente Opux X line in that they are double banded with a gold and red band on a black background.
