As an eau de toilette, Fcuk 3 has a lighter concentration of fragrance oil. While EDTs usually last around three to six hours, this fragrance may last longer depending on a wearer's body chemistry, environment and application style. Fcuk 3 can be purchased at major department stores, but FragranceX is a solid option for buying perfumes and colognes online. FragranceX sells authentic, quality fragrances at discount prices, allowing you to save up to 80% off.
