Robusto - 5" x 50. Oliva Serie O is a Nicaraguan Puro. Made in the original Cuban tradition of growing the same Habano seed in diverse regions of the country to produce a distinct blend. This blend was achieved by growing Habano in Esteli, Condega and Jalapa Valley. Blending Notes: Notes of dark tobacco with spice and rich cedar. Aging: Puros should be aged at generous humidity levels (70-78%) to preserve the natural oil.
