Which type of nail art requires the use of a dotting tool?

Polka dot designs are specifically created using a dotting tool, which allows for the precise application of small, uniform dots of nail polish on the nail surface. This tool typically features a rounded tip that can create various sizes of dots, making it ideal for achieving the clean, distinctive look of polka dots. The technique involves dipping the tool into polish and then pressing it onto the nail, ensuring that each dot is evenly spaced and consistent in size.

While striped designs, floral designs, and ombre designs may require different tools or techniques for their execution, they do not rely on the unique functionality of a dotting tool to achieve their respective aesthetics. For instance, striped designs generally use striping brushes or tape, floral designs may involve brushes or nail art pens, and ombre techniques often employ sponges for blending colors. Thus, polka dot designs are uniquely suited to the precision that a dotting tool provides.
