Absolutely waterproof, non-fading, lightfast and with wonderful tips with which to draw. No idea if they are archival but they are supposed to be acid free which simply means that the ink is PH neutral and should not cause your paper to deteriorate over time if you have gone to the trouble of sourcing archival papers on which to work. Being light resistant makes the MyLifeUNIT Technical a great art tool as work can be displayed without fading even under continuous exposure to light. MyLifeUNIT Technical are ideal for graphics, manga, design, illustration and technical drawing.
