Cute and practical sign set is a terrific teaching aid about traffic signs, a fun way to designate "children at play" areas and more. Includes an 11" x 11" x 1-3/4" base that can be filled with sand or water, a 20-1/2" pole, a realistic looking 11" octagonal Stop sign and a blank white sign compatible with most write-on, wipe-off markers and write-on, wipe-off crayons. To clean the blank sign, simply use water or a mild cleaner like Windex. Use the blank sign to create your own custom signs.
