Kuretake White ink is highly opaque and perfect for making corrections or producing distinctive highlights. You can dilute this ink with water to change the consistency and opacity. To get a stronger solid line you may want to apply several layers of this ink after each layer has dried. Depending on the dip pen/brush you’re using you will need to change the consistency of the ink. It is completely smudge proof and waterproof when dry but can take up to two days for it to dry fully.
