The Pebeo 4Artist marker line offers bright, highly pigmented oil colors with a high gloss finish and a paint-like texture in a marker. These artist-grade markers apply smoothly and dry quickly to a homogeneous, scratch-free finish. Just like oil paints, both wet and dry colors can be reworked using 4Artist marker odorless medium to create an array of shades, color gradients and fading effects on most surfaces. Permanent and lightfast, they are ideal for drawing, outlining, filling in large areas, glazing, mixed media, and more. Comes in 18 opaque colors. Available individually in 2 mm, 4 mm, 8 mm, and 15 mm tip sizes, as well as in a variety of different sets. Ap certified.
