This is a top quality item. Complete with weighted base, these 15" Traffic Safety Reflectors or exceed all OSHA & ANSI codes so you can use them in complete confidence. This is one of those items you are better off having in your trunk and never needing, than needing and discovering it isn't there. And at this price you can't possibly resist so get them while they last-- we've got a limited supply of these and this is a closeout.
