4-Mil blue disposable ambidextrous gloves are made of co-polymer nitrile, a new non-latex process that has better tensile strength & elasticity than nitrile alone, yet has full barrier protection. Powder-free gloves have excellent fit & feel, good sensitivity, while protecting hands, reducing fatigue, & helping prevent cracked, dry skin. Thin & strong, co-polymer nitrile has the advantage of losing its "memory" in less than 10 Min. This reduces stress on the muscles of the hand, & acts like a support stocking, stimulating but not tiring the hands the longer the glove is worn. The low-modulus, hypo-allergenic formula keeps hands feeling cooler & drier, & it is more abrasion & puncture-resistant than vinyl. At the same time, nitrile also has the advantage of disintegrating immediately if a puncture does occur, alerting the operator that the glove must be replaced. Gloves fit right or left hands & should be worn once, then thrown away.
