What tool is essential for achieving detailed designs in nail art?

The detail brush is essential for achieving intricate and precise designs in nail art due to its fine bristles and narrow shape, allowing for greater control when applying polish or creating designs. This tool is designed specifically for fine lines and detailed work, making it ideal for artists looking to enhance their nail art with more complexity and precision. The ability to create thin, delicate strokes is crucial in nail design, especially for techniques like painting intricate patterns, floral designs, or adding tiny accents that elevate the overall appearance of the nail.

While other tools may serve specific purposes—such as the flat brush for broad strokes or the sponges for blending and ombre techniques—the detail brush distinctly stands out for its role in producing detailed artwork on nails.
