All lip brushes should be this shaped.
It just makes sense. The straight edge provides a precision application of your lipstick. I will never use another lip brush again.
This brush is used to define the lip contour, it gives precise definition of a shape or modifies it.
Type of fibers: Straight.
Recommended textures: Lipstick and gloss.
Its geometric head is used to line the lip contour easily. Use the flat side to fill in and color with any lip product.
Pro tip: Its flexibility is used to blend Aqua Lip pencils easily to create long-lasting, waterproof base on the lips. Use its straight and fine tip to draw lines for a variety of effects with eyeliner.
