Letraset Promarkers offer great value and top performance. Each pen is double-ended with a broad chisel nib for large area fills and a fine bullet tip for more detailed work. ProMarkers produce vivid, bright colours right through to the subtlest pastel shades - the translucent inks can also be overlaid and blended, even further extending the range of shades and hues on offer. ProMarker's quality nibs and inks provide flawless colour lay down with consistent coverage and no unsightly streaking. Promarkers contain alcohol based inks.
