These are Winsor and Newton's finest acrylic paints - they're made with the latest developments in resin technology. Most acrylics darken as they dry, but our clever, translucent binder means that what you see is what you get. With no color-shift, color-matching is made much easier. We've also made sure these paints have a longer working time without compromising the famous acrylic fast-drying time. And, with 80 brilliant colors, you're spoiled for choice.
