The Ateco Black Nylon Counter Duster is manufactured through a process called epoxy fusing in which the bristles are planted into molten epoxy. When the epoxy cools and hardens, the brush is impervious to moisture. Since 1905, Ateco has manufactured tools to help professionals as well as enthusiasts create extraordinary looking cakes, cookies and pastries. Ateco products begin with the finest materials, from metals to fabrics to plastic films and undergo testing for durability, reliability, and quality. They are made to last under the punishing conditions of restaurant and high-output commercial kitchens. Made in USA.
