Dual‑tip fabric markers with fine and broad nibs for crisp details and bold fills. Permanent on most cottons after heat setting and washing instructions are followed. Low‑odor, non‑toxic ink is suitable for tees, totes and décor projects. This 10‑piece set features primary colours to mix, shade and letter cleanly without bleeding through most medium‑weight fabrics. Pre‑wash or heat‑set as applicable to control shrinkage, improve colorfastness and finish.
