Spectrum Noir pens are alcohol ink based markers. They are fast drying, acid-free and non-toxic, and the colored ends of the pen allow for easy color identification. Each pen is double-ended, with a broad chisel nib for large area fills and a fine bullet tip for detailed work.

These six color-themed marker sets were created intentionally so that from a single set of pens you will always have colors which are perfectly co-ordinated and work together. Spectrum Noir markers are available in 168 color shades including a colorless blender (in the Essentials Six Piece Set). The colors blend seamlessly, and can be mixed or layered over each other.
