This 1941 Replica Brushed Chrome casing has flat planes with sharper, less rounded edges where the front and back surfaces meet the sides. The lid and bottom are joined with a four-barrel hinge and the inside unit is flatter, with edges where they meet the front and back surfaces. It’s packaged in an environmental friendly gift box. As with all Zippo Lighters, it comes with a Lifetime Guarantee. We recommend to fill with Zippo premium lighter fluid.
