OAS Fine Detail brushes do the finest lines. The brush's size, shape, and compactness resists both color and ink overloading.
In the past, OAS carried three sizes, S/M/L - Super Fine Detail [1/8" x 5/8"], and Fine Detail Large [3/16" x 13/16"]. However, both Super Fine and Fine Detail by OAS' choice have been discontinued due to the consistent price inflation on the brush. We apologize for the inconvenience.
