Unlike traditional coloring tools, these washable markers let artists draw and doodle on windows, mirrors or frames. They can also be used on items like ceramic tiles, rocks, glass and much more. Kids can feel free to use these Crayola markers for words, pictures and doodles while adults can use them for glass writing or as car window markers. This marker pack comes with an assortment of colors for creating opaque, vibrant designs. Formulated with washable ink, stray smudges are easy to clean from skin and most clothing.
