Small but mighty, the Kei S wallet from Acne Studios promises to keep your daily essentials stowed safely within its minimalist interior. This curved silhouette has been crafted in Italy from smooth leather in a pastel powder-pink hue. The compact design features credit card slots and a pocket for cash and receipts. A wrap-around silver-tone zip and the brand's lettered logo cinch the piece with contemporary elegance. Slip yours into one of the label's coveted Musubi totes or carry it in hand for your morning coffee run.
