100% natural horsehair bristles provide smooth, even application while resisting shedding, and strong tin metal fluted ferrules keep the bristles tightly secured. The tubular handle is comfortable to hold, offering good control, helping reduce drips and improving accuracy on detailed work. Specs: each acid brush features a 5-1/4 inch tubular metal handle for durability and balance, with a 7/8 inch long by 3/8 inch wide horsehair bristle head. The 3/8 inch ferrule holds the bristles firmly in place, and the overall brush length of 6 inches offers excellent reach in tight or recessed areas. Economical handy tools for applying a wide variety of materials on interior and exterior projects, including glue, acid, flux, oil, paste, pipe dope, soldering compound, grease, zinc primer and more. Ideal for touch-ups, spreading, dusting and cleaning, they suit hobbyists, DIYers and professional users alike. Versatile brushes that also work well for cooking and baking applications, applying butter or oil in small areas, as well as for art, woodworking, model building, school workbooking and general arts and crafts. Their compact size makes them easy to control for fine detail, edging and tight-spot coverage. Sturdy brushes designed to perform reliably whether you reuse each brush multiple times or treat them as disposable for one-time jobs. The metal handles resist bending under normal use, while dense horsehair bristles hold liquids effectively, making these 48 count brushes a practical shop staple.
