What does 'e-file' refer to?

The term 'e-file' specifically refers to an electric filing tool used in nail enhancement services. This device is designed to efficiently and effectively shape and smooth the nails, especially when working with acrylics or gel enhancements. The e-file operates at various speeds and can be equipped with different bits for versatile applications, such as refining the nail shape, removing bulk material, or even prepping the natural nail for enhancements.

This tool is especially beneficial in a professional setting, as it allows for precision and speed, reducing the time required for services compared to manual filing tools. Its ability to minimize hand fatigue while providing consistent results makes it a popular choice among nail technicians.

The other options do not accurately describe the e-file: a manual tool for filing nails refers to traditional hand-held files, a type of nail polish application technique is unrelated to filing, and a method for soaking nails involves the use of liquids to remove products or prepare the nails, which is quite distinct from the function of an e-file.
