Jil Sander Perpetual Calendar Key Ring
Crafted from discs of leather, Jil Sander's Perpetual Calendar Key Ring is an unexpected EDC addition. The black leather panels represent the day, month, and day of the week, working from outside to in. A central flap has openings to note the current day, while a silver-toned metal clasp holds the whole thing together. Made in Italy, it measures four inches across and over eight inches long.
