You´ll be "on a roll" with paint and clay craft activities as easily as using a rolling pin with this great set of 4 designs. The clever styles include a dot pattern of various sizes in a random array, a wave pattern, zigzag squiggles, and parallel, multi-width stripes. All rollers are 7" long and 1.5" in diameter and made of very durable plastic and hard rubber. Soap and water are all you need for an easy clean-up. Both the young and the young-at-heart will be very creative while developing coordination skills and artistic interests! Includes 4 rollers per pack. For ages 3 and up.
