ALMOST perfect.
Color: Vivid Orange
Item is as advertised. Durable, and the tools are useful for more than just regular plugs. It comes with the snips which was great as well as actual valve stem replacements which I thought were pretty nice. Only complaint are the plug strips themselves. If the hole is from a bolt or something larger than the average screw, it may take two of them to completely stop the leak. Hope this helped.
