Review on Koh-I-Noor Pigment-Based Universal Drawing Ink, 0.75oz Bottle, Black - Professional-Grade Art Ink by Gelin Battle

I bought this ink specifically because I needed waterproof ink for my illustrations - I'm so disappointed because this ink is definitely NOT waterproof. After letting it dry completely I tried to do a few watercolor strokes over it but the ink spread and smudged the watercolor. The mascara itself is a beautiful deep black, if you use it alone you will love it. But stay away if you need something that can withstand water! (I'm confused because there are so many reviews saying the ink works well with water, so I'm not sure why my experience is so different. The bottle I received didn't have the same label like the photo (It looked rather informal compared to the product image shown here. Hmmm, suspicious.)
