You can achieve beautiful effects with these 24 quality chalk pastels. Each chalk measure 3/8" square and is 2-1/2" long.

Use them for scrapbooking and rubber stamping projects, on ceramic bisque, on almost any type of paper including grocery bags and also for fine art projects. Once applied the chalk will not smear or rub off but a spray fixative can be used to protect the surface. Cleanup is with water. The selection of colors includes all the essential art colors which can also be blended together for special effects. Included in this selection are white, black, brown, turquoise, violet, magenta, red, orange, peach , dark blue, blue-green, red-violet, ochre, yellow, yellow-green, earth,grey, red-orange, green, light blue, blue, burnt sienna, dark green and yellow orange. PLEASE NOTE: Despite careful packing soft pastel sticks are often subject to breakage during shipping and handling. Professional artists recognize this as common with these products but it does not affect their usability or results.
