A box press cigar starts out round. After it comes out of the mold, it is pressed (in a box, between boards, or in a press) so its sides flatten and it gets corners. Padrón’s 1964 and 1926 lines are well-known box-pressed Nicaraguan puros; the company describes its pressing as being done in the Cuban style.
Pressing changes the draw slightly and the appearance a great deal. It does not change the blend. If the factory says so, a box-pressed robusto uses the same leaves as the round version.
A box-pressed cigar is not a figurado. It is still a parejo, just with a different cross-section.
