Nothing tops a classic. Classic Tobacco is the original blu e-cigs flavor: a carefully crafted, proprietary blend of Burley and Brightleaf tobacco flavors. Then, the flavor of flue-cured Cavendish is added to the mix, bringing out the natural sweetness. For those who enjoy the taste and feel of a rich, full-flavored tobacco cigarette, Classic has you covered. It IS the electric cigarette flavor cartridge of choice.
