Which items are considered single-use disposable items in sanitation practices?

The correct choice identifies flip flops and non-metal nail files as single-use disposable items in sanitation practices. Single-use items are designed for one-time use in order to prevent the transfer of bacteria and maintain hygiene standards.

Flip flops, often used by clients during services such as pedicures, prevent direct skin contact with surfaces while ensuring that each client has a clean pair for their visit. Non-metal nail files are typically made of materials that can be easily discarded after use without compromising sanitation.

On the other hand, items like scissors and tweezers are tools that are usually sanitized and reused. Hairbrushes and combs also belong to the category of reusable items since they are often cleaned and disinfected between uses. Reusable towels, as suggested in the last option, are also intended for multiple uses after washing, making them unsuitable for classification as single-use disposable items.
