Crayola Ultra-Clean Washable Fine Line Markers are designed with ColourMax technology to provide vibrant and high-quality colours. With a fine tip, these markers are perfect for detailed coloring and precision work. Unlike other markers, they are long-lasting and won't dry out easily. If the tip does dry out, simply dip it in room temperature water to rejuvenate it. The Ultra-Clean Washable Ink is specially formulated to come off machine washable clothing, as well as walls, carpets, and furniture with warm water and a sponge. This set includes 10 classic colors, suitable for ages 4 and up.
