A double-ended instrument, with broad and fine acrylic filament nibs, that can be used to apply any water-based medium. It is especially designed for silk and fabric painting but may be used for applying other water-based mediums and liquid frisket to a variety of surfaces such as watercolor paper, board, canvas, cotton, wood and clay. It can be used just like a brush to lift out, soften edges and blend. The points stay firm when wet so they can be used along a straight edge. Comes with instructions.
