Which of these items is NOT considered a disposable material?

Metal tweezers are not considered a disposable material because they are designed for multiple uses and can be sanitized. Unlike disposable items, which are meant to be used once and then discarded to prevent cross-contamination and ensure hygiene in a salon or spa setting, metal tweezers can be cleaned and reused safely.

Other items, such as cotton swabs, disposable spatulas, and gloves, are intended for single use. They are thrown away after one application to maintain cleanliness and safety, making them essential tools in practices where client health is prioritized. The emphasis on disposability is particularly important in esthetics to reduce the risk of spreading bacteria or infection.
