    it says right on the box.

    however, keep in mind, over time, the sponge in the ink dries up and makes the ink dry up with it, so you may end up with less the longer you wait to use it.

    None. Ink is not measured in millimeters. It is measured in milliliters or ounces.

    And the answer is just a few, most contain about a half ounce.
