Call the family mechanic about a rough idle and he will usually offer a verdict before hearing the engine at all. More often than anyone admits, the verdict is the plugs. This fob gives him his favorite diagnosis. A single spark plug stands upright at the top with its electrode gap left open. Probably sits beneath in brush script over THE PLUGS in engraved capitals.

Gray sand is a pale, earthy neutral that lets the pressed plug read clearly. The design is sunk into full-grain leather with a metal die and kept to one side of the fob. Every keychain is cut and finished by hand to order, and gold foil is available at checkout.
