This is the money clip made from kangaroo leather—the strongest leather in the world. Available exclusively from Hammacher Schlemmer, the wallet‘s  tight, dense kangaroo leather provides four times the tensile strength and three times more abrasion resistance than cowhide or deerskin. Two-times thinner than traditional hides, kangaroo leather can be rendered to 1/4" thin for comfortable storage in a front or back pocket without compromising the leather’s strength. The Australian kangaroo leather is naturally water-resistant and it will never fade, crack, or unravel. The money clip presses closely against the wallet to hold a single bill as tightly as it secures 20. With four credit card slots. Black. 4" L x 3" W x 1/2" D. (4 oz.)
