The cigar is a robusto extra vitola that measures 5 1/2 inches (140mm) long with a 54 ring gauge, a vitola with the factory name Duke. It is a vitola that debuted in 2009 with the Romeo y Julieta Dukes, an Edición Limitada, and has since been used for the Partagás Serie E. No.2 and a number of Edicion Regional releases.
The release, which was commissioned by Coprova, the distributor of Habanos S.A. products in France, is limited to 20,000 individually numbered boxes of 10 cigars, a total run of 200,000 cigars.
This is the second time that the Por Larrañaga brand has been selected for a French Edición Regional; in 2015 the Por Larrañaga Opera was released, a 4 1/2 x 52 petit robusto, with the cigar getting a re-release in 2016.
The Prometidos is one of five Por Larrañaga Ediciónes Regional that are part of the 2021 class.
