Showa Best 9905 Powder Free Gloves. Called the Ultimate Nitrile Glove by Showa Best because it's about 2 inches longer than other Nitirle Gloves providing additional coverage for the user's wrist and lower arm and just a bit thicker than typical Nitriles with these Gloves being a thickness of 6 mil. A good choice for many applications and will hold up longer than other Nitriles due to its added thickness and resistance to cuts, snags and abrasions.
