The soft color and raised line of Souffle add dimension to Diy craft projects. This unique 3D ink leaves a tactile, elevated line that stands out on plastic, coated paper, acetate, vellum, and glass—especially on dark backgrounds. Simply write slowly to let the ink flow, then allow time to dry for best results. Souffle pens are ideal for personalizing items with names or dates. Certified non-toxic and Acmi approved. Not intended for lengthy writing.
