Normal sized cigarettes with good filter.A reputed product of marlboro also known as "marlboro red" because of its red packing, it is readily available to the smokers and has a very large no. of consumers.
I enjoy its smooth flow as well as the feel of a high end product.Although, its successor marlboro advanced is more famous now a days, regular still has its large consumer base.
So if you want a mild taste and a royl feel, try it out.
