CK One (Eau de Toilette) by Calvin Klein is a fragrance for men and women, introduced in 1994. It opens with zesty, invigorating top notes, moves to delicate, floral heart notes, and settles on warm, earthy base notes for a fresh, contemporary signature. This versatile scent is ideal for daytime wear, offering a clean and modern aroma that suits both casual and professional settings. Our 0.75 ml sample vial delivers 10-15 sprays, making it a low-risk way to explore a fragrance without commitment.
