Dixon China Markers make beautiful bold strokes on almost any porous or non-porous surface including glass, plastic, film, paper, metal, and rubber. The writing marks wipe away clean from porous surfaces. Dixon China Markers are excellent for use in various industries where a quality writing tool is necessary, such as construction or handyman work. They make great marking pencils for use in bibles or textbooks, chemistry labs, marking food storage bags, or pricing items for garage sales. The possibilities are endless! There is no need for a sharpener since each pencil is wrapped in paper with a tear string for easy sharpening. Available in a selection of bright, brilliant colors, each Dixon China Marker is PMA certified non-toxic, so they are safe for all ages. Today the Dixon Ticonderoga Company continues to make our mark manufacturing and marketing writing instruments, art supplies and tools for self-expression, making each of our products The Best of its Kind.
