"emery board" の定義と意味

What is an "emery board"?

An emery board is a small, rectangular, or curved file made from a thin strip of abrasive material, typically coated with emery or sandpaper. It is used for shaping, smoothing, and refining the edges of the nails. With its rough surface, the emery board effectively files away rough edges, uneven lengths, and jagged corners, providing a smooth and polished finish to the nails. Its compact and portable design makes it convenient for on-the-go nail maintenance. The emery board is a versatile tool commonly used during manicures and pedicures, allowing for precise nail shaping and achieving desired nail lengths.
