Anna Sui Fantasia Mermaid (W) Set Edt 5Ml + Bl 30Ml

Perfume sets often include multiple items designed to complement each other. In this case, it seems to be a set with two items: an Eau de Toilette (Edt) and a Body Lotion (Bl).

Eau de Toilette (Edt):

Edt is a type of fragrance that contains a lower concentration of perfume oils compared to Eau de Parfum (EdP). This makes it lighter and less overpowering, making it suitable for everyday use.
The 5ml quantity suggests that you’ll receive a small bottle of Eau de Toilette. This is a common size for travel or for trying out a new fragrance before committing to a larger bottle.
