Which item is an example of a single-use item?

Finger cots are considered a single-use item because they are designed to be worn once and then discarded to maintain hygiene and prevent cross-contamination. In esthetics and other personal care practices, the use of single-use items is critical for protecting both the client and the practitioner. Once a finger cot has been used during a procedure, it should not be reused due to the potential risk of spreading bacteria or pathogens. This ensures a safe and sanitary environment for every client.

On the other hand, the other options generally involve items that can be reused or cleaned. Facial sponges can often be laundered and sanitized, reusable towels can effectively be washed and reused multiple times, and makeup brushes typically require thorough cleaning between uses, although they can also be reused several times. These aspects make them different from single-use items like finger cots, which are meant to be discarded after one-time use.
