Over 300 professional artist markers (I think it’s closer to 400). The Letraset PorMarkers are alcohol based artist markers. Similar to Copics. Very high quality markers made in the UK. Letraset was bought out by Winsor Newton. This includes many limited edition colors, almost the entire line of promarkers and a marker airbrush. Also included is many ultra fine tips that can be snapped onto the markers. Several markers already have them on. Most markers were only used to make a small square sample to see how they looked on paper. There might be a few markers that have dried out.
