Overview:

Manufactured from high-temperature steel core/graphite faced exhaust material. Expanded steel core provides stability and maximum torque retention to eliminate gasket failure. Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head. Conforms to and seals minor surface irregularities. High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load. Can be trimmed if necessary for modified port applications. For original equipment replacement, high performance street, drag race and oval track use.

    Nice Idea But Won't Last With A Frenchie
    Color: orange & blue, Color: orange & blue
    My dogs loved the balls, however, withing 30 minutes, they were in pieces. Be careful because these parts can become choking hazards. Maybe they should try to make them a bit more sturdy, then I would buy again. Wish I could give them more stars because I liked them and the dogs did too.

    Not a chew toy
    Color: red&green
    Our dogs love these! The dogs play for about a half hour then they get tired ,they pick it up by the string and toss it around , only important thing, supervise play time !!! This will break if chewed on , this is not a chew toy , put away once your dogs are done with it .

    Fits Cats not Dog size
    Color: red&green
    Sure these balls are cute, but most definitely not a dog size. I wouldn’t waste your money, unless you own a cat!

    Not durable
    Color: red&green
    The description says for cats and dogs. My 6lb mini poodle tore it up in less than 40 minutes. The red one worked but the green one wouldnt even turn on. The indicator said it was fully charged but u plugged it in for a short time but nothing. I dont know if i can get a refund or not since the cover on the red one has been completely torn off. I dont recommend this product
