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, chemical-resistant, non-magnetic, stainless 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 1/4" at the tapered end, and 1/2" at the flat end. The handle dimensions are 4-1/2" length x 3/16" diameter, and a flat brush width of 1/4". This brush is a great alternative to hand-trimming acid brushes.
