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 bright 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.
