The RIDGE carbon fiber slim card case with money clip. - Brand: the RIDGE - Material: Carbon Fiber - Color: Black The card binding strength can be adjusted with the included screwdriver. It can hold from 1 to 15 cards, and it's easy to use with a design that allows cards to pop out when pressed with a finger. (※ Personally, about 3 to 5 cards is just right.) Please note that returns and exchanges are not accepted. Thank you for viewing.
