Chloé's Envelope card case is crafted from supple goat leather with a garnet finish and jade green undertone, defined by contrasting black painted ribs. The envelope silhouette features the iconic gold Horse medal engraved with the Maison's equestrian motif on the front, a snap flap closure, and an upper zip compartment. The back accommodates four card slots and one flat pocket for essentials in a minimal, sophisticated design.
