The ink is manufactured with a water base and contains no toxic substances, no acid, no formaldehyde, and no heavy metals. The ink is hygroscopic, meaning that it self regulates by absorbing the humidity of the surrounding air so that it does not dry out, allowing prolonged usage.
Replacement ink cartridges are available in black, blue, green, red and violet.
