Review on 🖤 Koh-I-Noor Ultradraw Pigment-Based Ink - 0.75 Ounce Bottle - Black (3085F.BLA) by Rhonda Babson

I've been using this ink for years and swear by it. I illustrate all my published crime, non-fiction and now children's books with Ultra Draw. This ink allows you to keep your drawing underwater and it will not fade or wash off. I even painted with it on glass. The real reason I'm commenting on this is because I came across a great way to clean my Ultra Draw tips and Tech tips. The only problem with waterproof ink is cleaning the tools. I put a spray cleaner called Scrubbing Bubbles in a glass of water. You drop the pen and the water instantly turns black. Hope this tip helps. This definitely works for me. Robert Graysmith
