0.4 oz bottle of Speedball’s high-quality ink. All these inks are acrylic, except for the black, which is India ink.

Did you know? Acrylics weren’t invented until the mid-1900s. In the American colonies, iron gall ink was commonly used for writing. This type of ink was made by fermenting the fluids drained from a “gall,” or an abnormal growth on a tree. It was favored due to it being waterproof, but acrylics are waterproof, easier to make, & come in a wide variety of colors.
