The soft color and raised line of Soufflé add dimension to DIY craft projects. Three dimensional (3-D) ink leaves a raised ink line for writing you can feel. Soufflé pens color on plastic, coated paper, acetate, vellum and glass. One-of-a-kind, 3-D Soufflé ink comes in soft pastels and white, all of which dramatically stand out on dark backgrounds. No need to shake, pump or squeeze – just write slowly to let ample ink flow from the tip and allow time to dry completely.
