This is the GloveWorks Black Nitrile, a premium Industrial Grade disposable nitrile glove that is 30% thicker than standard nitrile gloves for added durability, so that each pair of gloves lasts longer while you're working. GloveWorks Black Nitrile gloves feature excellent protection against common chemicals, like carburetor cleaner, and many other specialty chemicals, such as iodine and butane, that you may encounter on the job. The glove holds up to brake fluid and, even after being dipped in gasoline, stays true to form. Work environments are always changing, and in wet or dry conditions you're going to need a strong grip. That's why GloveWorks Black Nitrile gloves are micro-roughened on the palm and textured on the fingertips.
