For Mercedes-Benz CLS-Class C257 Armrest Storage Case (Cannot be installed on vehicles equipped with MBUX-NTG6. As another easy way to tell, if the USB cable slot inside the console box is USB Type-C, it cannot be installed.) This item allows for more effective use of the storage box in the armrest. It can store coins, mobile phones, etc. Installation is as simple as opening the armrest and snapping it in! A used item from the third image is included as a bonus.
