The banana-shaped paper nail file is an essential tool for nail care, as it helps shape and maintain them properly. With a hardness of 100/100, it offers the same performance on both sides, making it ideal for the construction and finishing of artificial nails. Its banana shape allows for easy access and shaping of the sidewalls, while also protecting the cuticles from possible injuries. However, its use is not recommended for shaping the body of the nail, as it may cause deep grooves.
