Unique Aesthetic Appeal: The rectangular or square shape of the bottle provides a distinct and modern aesthetic compared to traditional cylindrical bottles. This unique design can attract attention on store shelves and contribute to a brand's identity.

Space Efficiency: Rectangular or square bottles are often more space-efficient compared to cylindrical ones. They can be arranged neatly on shelves or in storage areas without wasting space, making them ideal for crowded retail environments or compact storage spaces.
