Here is a breakdown of the fragrance, which is the key characteristic of this product:

Fragrance Profile: It is a Citrus Aromatic fragrance. The scent is known for being fresh, clean, and light, making it a very versatile and popular choice for everyday wear.

Scent Notes: The number "19" in the product name and "CK One" on the packaging directly indicate that this fragrance is a clone of Calvin Klein's CK One. The notes would therefore be an imitation of the original:

Top Notes: A bright and zesty blend of Bergamot, Lemon, Pineapple, Mandarin Orange, Green Notes, and Cardamom.

Middle Notes: A delicate floral and spicy heart with notes of Jasmine, Rose, Violet, and Nutmeg.

Base Notes: A clean and woody dry down with notes of Musk, Amber, Sandalwood, and Cedar.

Product Type: This is an Eau de Parfum (EDP), which means it has a higher concentration of fragrance oils than an Eau de Toilette (EDT). While it won't have the same lasting power as the original designer fragrance, Smart Collection EDPs are known for offering decent longevity for their price point. The "Pocket" designation means it comes in a small, travel-friendly bottle, typically around 15ml or 20ml, making it convenient for carrying in a bag or pocket for a quick refresh.
