Natural American Spirit Blue King Box cigarettes are the original flagship blend from Santa Fe Natural Tobacco Company, sold at Costco in a case of 12 cartons. Each pack contains 20 King-size cigarettes made from 100% whole leaf, additive-free premium tobacco with no reconstituted tobacco, chemical additives, or preservatives.

The Blue variety is the full-bodied, full-strength expression of the American Spirit line, featuring premium Virginia tobacco sourced from carefully selected farms. The absence of chemical additives produces a slower, more even burn and a clean, complex tobacco flavor without artificial aftertaste. The cigarette paper and filters are likewise free of chemical treatments.

Founded in 1982 by the Santa Fe Natural Tobacco Company in New Mexico, the Blue Box is the brand's original and most popular variant. The brand was acquired by Reynolds American in 2002 and is now distributed nationally. The distinctive blue packaging displays the brand's iconic Native American profile logo and prominently features its 100% Additive Free designation.
