Grimas Ox-hair Brushes are intended for face-painting with Grimas Water Make-up. Ox-hair Brushes are flat brushes with a straight top. The brushes have a red stem. The hairs of the 2mm brush can be cut off at an angle to allow finer work (e.g. modelling eyebrows, camouflage). Ox hair requires more control, so apply gentle pressure when working with these brushes.
