Intensely black and very waterproof, this ink can survive freezing temperatures...in case you happen to be sitting outside in freezing temperatures, while writing.
This scan was done on an HP Deskjet F4280 at 600dpi.
Because these scans are done with a light emitting printer, actual
colors will, more likely than not, be slightly darker than they may
appear, here. The
colors shown, here, are probably a bit more reminiscent of what the ink
would be like under a bright light or if it were held up and viewed
with a light behind it.
