For example, the Emininentes (see coronas table below) is currently produced by two brands or manufacturers, H. Upmann and Partagas.
H.Upmann sells it as 'Corona Major' and Partagas has two models in that size, the 'Coronas Senior' and the 'Petit Coronas Especiales' , but regardless of manufacturer or model name, all three are Emininentes and are exactly the same size and shape.
Outside Cuba most manufacturers, especially those established by Cuban exiles after the revolution, adhered to the Cuban factory-name system into the 1970s, but since then have introduced their own vitolas and naming, without any systemization across the industry.
Figurados are cigars that do not have straight sides, but are irregularly shaped, and have their own factory names, regardless of size.
