Roly traffic cone / traffic cone

Roly traffic cone

Traffic cones are important traffic safety facilities. Traffic cones on the road are easy to turn over on windy days or when they are hit by other cars.
Roly traffic cone consists of two parts, a base and a cone. It will not fall down that easy. Before we use it, we need to pour water into the base and the cone will be used as a funnel to make the pouring easy. The water in the base can be discharged quickly when people step on the top of the base. The base is light so it is convenient to transport.
