Showa Nitri-Dex Powder-Free Nitrile Gloves provide protection from chemicals. These unlined gloves offer heavy protection yet allow for the control and dexterity associated with lighter weight N-Dex gloves. Showa Nitri-Dex Powder-Free Nitrile Gloves feature a tractor-tread pattern on the palms and fingertips for added grip. The 9-mil thickness and 12-inch length are perfect for many applications. Showa used to package these gloves in a mixture of 25 right hand and 25 left hand gloves, so you had to sort through to find a set. Their new and improved packaging pairs the gloves, a right with a left, with a dozen pair in a package. This makes it much easier to find a pair when you need them!
