A multi-sided implement designed for fingernail and toenail care, this tool typically features four distinct surfaces, each serving a specific function in the shaping, smoothing, and buffing process. For example, one side might be coarse for initial shaping, while another is finer for smoothing rough edges.
The utilization of such an implement offers several advantages over single-grit emery boards. It consolidates multiple steps into a single tool, streamlining the manicure or pedicure process. Furthermore, consistent use can contribute to healthier-looking nails with enhanced shine. Its development likely stems from the desire for a more comprehensive and efficient nail care routine.
