Kids Coloring Ultra Washable Markers are an ideal choice in the home and at school for long-lasting, creative coloring and drawing projects for kids of all ages. They feature a blocked tip design that resists being pushed in, so young artists can use added pressure without smashing the marker tip. The bright, ultra-washable ink rinses easily off skin and most clothing, making cleanup simple. If the caps are accidentally left off after art time is finished, no need to worry. These markers wont dry out for days or weeks (average cap-off times vary by color: one week to one month for most colors, four days for Brown, Madder and Atlantic Blue, 24-48 hours for Red, Pink and Purple).
