The Sweet Sticks Lustre Brush has a cylindrical flat end and is great for wide strokes where coverage is required. If you are working on a surface where a wash brush might be too large, this Lustre Brush gives you excellent coverage while also providing you a little more control over the wash brush. This brush is perfect for buffing the Sweet Sticks Lustre into surfaces to either lightly coat a product or buff out lustre application imperfections.
