The M-Series Chassis Clip is an accessory to all Maverick Wallets, and best for single pocket variants. This accessory helps you to hold cash, more cards and allows you to clip your wallet to your pant pocket, belt or bag strap. In addition, a bottle opener is discreetly designed into the clip so that you will never be short of popping a beverage!
