Back to school milestone boards are perfect for celebrating your family's first and last days of school. They are great for watching your children grow each school year, or using in classrooms for students! Boards feature classic school-related images. Our in-house artists have created original chalk artwork of a schoolhouse, bus, slide, and utensils using liquid chalk markers on chalkboards. Artwork is digitized and embedded onto the boards. Faint guidelines help write straight. The matte chalkboard style surface reduces camera and lighting glare. Select from four marker sets: one white marker, three bright markers, three pastel markers, or no markers. Cohas markers feature a reversible 2mm bullet and 6mm chisel tip on each end. The wet-wipe ink will remove with water, but won't smudge. For best results, shake markers between each use, prime on scrap material, and wipe away immediately after use. Boards have been tested and approved for quality liquid chalk markers. If using your own markers, test for staining on the provided swatch. Don't use regular chalk, dry erase, or permanent markers. Boards are offered in three sizes and sets. Choose from 9 by 12 inches, 12 by 16 inches, or 15 by 20 inches. Sets come in First Day of, Last Day of, and First and Last Day pairs. Made with a recycled wood material, the signs hold up against each use. Finished edges and rounded corners help prevent scrapes or harm to little fingers. Cohas products are always made in the United States!
