The Daler Rowney FW Pearlescent Effect Ink Set contains 6 x 29.5ml bottles. The colours included in this set are; Black, Moon Violet, Waterfall Green, Galactic Blue, White Pearl and Platinum Pink. Having taken advantage of developments in the pigment industry, this range is able to give a brilliant shimmering pearl effect. Such a degree of lightfastness over a range of fully intermixable colours makes them ideal for use by artists in the production of pictures for permanent display. Ideal for use with a dip pen, ruling pen or brush. They are permanent and translucent, but work best when put down freely, where colour strength, expression and fluidity are required. Since they are water based acrylic inks, you still get a startling pearl effect even after dilution with water.
