Yarka St. Petersburg Artists' Watercolour Pans are manufactured in a 100-year old Russian paint factory. Each pan is liquid poured instead of the compressed extrusion process used by many other manufacturers. This means that every watercolor has a soft, rubbery feel that never totally dries in the pan. Unlike painting with other pan colors, activating Yarka watercolors just takes a swipe with a wet brush. No needless scrubbing and wear on your fine brushes. The pigment used to create each paint enhances the texture of any watercolor paper that you use. They are just unlike any other watercolor in a pan or a tube. So, make Yarka watercolors part of your art supply collection right now and see what so many artists love about Yarka!
