3 years & up. Set up a life-sized obstacle course using this collection of jumbo Traffic Signs. Constructed from a flexible, crack-resistant TPU material with UV inhibitors, each sign is durable enough to be used indoors or outdoors. Extra wide bases can be filled with sand or water to provide an additional sense of non-tip security. Each sign has a 10" base and measures approximately 29" tall. Store in a cool, dry place.
