Liquid Chalk Marker are a legendary blend of old-fashioned chalk and modern markers. They are made to be used just like paint pens but instead of producing paint, the liquid dries to look just like chalk. When used for acrylic painting, acrylic paint pens can help with adding highlights, lines, fine details, and text to paintings. They are great for use in abstract art, pop art, and graphic design art projects too! They can be used not only on canvas but also on wood, glass, ceramics, furniture, metal, paper, foam board, rocks, and even vinyl too! http://www.queenstarmarker.com/liquid-chalk-marker/
