Haas mustang Brush. This military brush can be used on softer coats as the outer bristles are longer than the other brushes.  Bright bays and chestnuts can have softer coats and so the Military is ideal for these coloured coats.Special synthetic bristles and special fine brass wire define this brush. This unique bristle combination, developed by HAAS makes this bush an ideal for cleaning thick or shedding coats.
