Disposable nitrile is a popular alternative to latex. Made from a synthetic polymer, they don't contain any natural rubber latex protein which can cause irritation or allergic reactions in those sensative to latex. The unique properties of nitrile also allow for a more snug fit as the glove reacts to body temperature and conforms to the hand. Black nitrile has unique applications in law enforcement, but also for tattoo artists and other medical professionals. Gloves are non-sterile, lot controlled, disposable and designed for single use only.
