This double-ended applicator brush has anti-static horsehair bristle. One end has a flat trim and the other end has an extra-stiff chiseled trim. The handle is made of lightweight zinc-plated steel. This brush is manufactured using strong mechanical clamping for maximum fiber retention, and is adhesive-free to prevent contamination on surface areas caused by leaching. This high quality brush has a trim of 3/16" at the tapered end and 1/4" at the flat end. The handle dimensions are 4-1/2" length x 3/8" diameter, and the brush width is 1/2" flat. This brush is a great alternative to hand-trimming acid brushes.
