To tout its famous lifetime guarantee, Zippo takes an amusing view this Valentine's Day in a campaign that focuses on couples whose flame has gone out. Print and video ads show couples with shared disinterest while copy alongside them that reads, "With a lifetime guarantee, there’s one flame that’s sure to last." The lighter brand is leveraging one of the biggest gift-giving holidays of the year to playfully remind people to give a gift that lasts, a Zippo lighter.
