Most cigars are parejo: even sides from foot to head, a binder and wrapper in a spiral, a cap on the head, the foot left open to light. Robusto, corona, churchill, toro, lonsdale, lancero are parejo names when they are not also used for shaped cigars.
A box press still counts as a parejo. The sides were round in the mold and square in the box. The silhouette is a cylinder that learned corners, not a figurado.
If the cigar tapers or closes at an end, see figurado.
