1. Colour & Effect: While the exact shade of No. 15 is not explicitly defined in the search results (shades often vary by retailer), the Colour Mix line typically includes shades ranging from peach to pink and berry. The gloss provides a semi-transparent colour and a voluminous shimmering or ultra-shine finish, while the creamy pencil offers excellent coverage and a defined base.
2. Formula & Texture: The product is formulated with oils that ensure the texture is compact and non-smudging, providing a comfortable, non-sticky, and lightweight film on the lips. The pencil is notably soft and easy to apply, providing a smooth base for the gloss.
3. Application: The dual format allows for versatility. You can use the creamy pencil to outline and fill the lips for definition, then apply the gloss for a lush, luminous pout. They can also be used individually to achieve different looks.

Benefits

1. Nourishing & Moisturizing: The formula includes beneficial components like almond oil, castor oil, jojoba oil, beeswax, and vitamin E, which help to moisturize, soften, and improve the elasticity of the lips.
2. Long-Lasting Wear: It offers a long-lasting effect, with the pencil providing a good base to help the gloss adhere, reducing the need for constant reapplication.
3. Volumizing Effect: The gloss delivers a voluminous, 3D effect, making lips appear fuller and plumper.
