Basic car warning triangle made of plastic. Its base does not seem very stable, and I do not believe that in case of wind it would stand on its own without some extra support; however, if that is overlooked, it will do the job. The case is made of cardboard, so it will fall apart easily, unless it already arrives slightly torn from shipping. It could have been in at least a basic plastic case, because outside the case it seems like it would break easily. For its price, though, to have it for an emergency, I cannot ask for much more.
