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 5 ml travel spray delivers 60-75 sprays for 2-3 weeks of wear, making it a best-selling size that’s perfect for everyday use and TSA-approved for easy carrying.
