Which brush type would be most appropriate for precise application of eyeliner?

An angled brush is highly suitable for the precise application of eyeliner because of its unique shape that allows for better control and accuracy. The beveled edge of an angled brush enables users to easily create sharp lines along the eyelid, which is essential for defining the eyes with eyeliner. Its design allows professionals to navigate the contours of the eyelid, providing a more streamlined application that can vary in thickness based on technique.

Other brush types may have their specific uses but do not offer the same level of precision for eyeliner application. A flat brush, for instance, lacks the ability to create fine lines and may result in a broader stroke than desired. A pencil brush is typically used for smudging or blending rather than for application, as it is softer and designed to create a more diffused look. The Maurice brush, while potentially a less common or specialized tool, doesn't typically pertain directly to eyeliner application, thus making the angled brush the most effective choice for this specific task.
