Made from genuine calfskin, a supple yet durable cowhide, the wallet resists the wear and tear of everyday use while remaining buttery soft. It has six interior slots that hold up to nine cards, a full-length bill compartment, and a snap fastener. The battery recharges in 30 minutes via the included micro-USB adapter.
