Non-porous implements are those that do not absorb moisture, making them less likely to harbor bacteria or pathogens. Metal tools and glass files are both made from materials that create a durable, rigid surface, which can be easily sterilized and disinfected. This quality is essential in a nail care setting, as it ensures that these implements maintain hygiene and safety standards.

Metal tools, such as nippers, scissors, and pushers, can withstand high temperatures and chemical disinfectants without being damaged, ensuring effective sanitation between uses. Glass files are also non-porous, and their solid structure means they can be sanitized properly and reused, reducing waste.

Other options include materials that are porous or less suitable for hygienic practices. For example, paper files and sponges can absorb liquids and may foster bacterial growth, while wooden sticks and cotton pads are also absorbent by nature. Plastic tools and brushes can vary; some may be non-porous, but many can become scratched or damaged, compromising their non-porous qualities over time. Thus, metal tools and glass files stand out for their durability and sterility, making them the correct answer.
