da Vinci's Cosmo Top Spin is the finest, extra-smooth, synthetic hair. It is a soft brush with colour holding capacity. This brush has amazing capillary-action for drawing-up, holding and releasing water and colour. It gives the artist exceptional control while painting.
Spin Synthetics are good for watercolour, ink, gouache, and fluid acrylics. This brush is also good for varnishing.
The mottler is a short handle brush and ideal for wide wash brushes because it provides amazing manoeuvrability.
