NEW! The Kaye card holder comes in box; the Sierra wallet doesn’t. The "Kayé" card holder features three expandable compartments, giving it the appearance of a small book. Bound together by a leather strap, it closes with a sliding gold-plated pebble and can be worn on the wrist. Dimensions : 7 x 11 x 3 cm. The “Sierra Wallet” incorporates two design features that are central to Polène's esthetic: rounded shapes and leatherwork in contrasting colors and trims. Dimensions: 19 x 10.5 x 3 cm
