This card holder is hand made of an authentic Louis Vuitton long wallet that I have. All of the materials are from that wallet including the canvas and slot parts. Since the wallet has discolored on the leather inside, so you can say those in the card holder, please check those pictures. The Costco membership card inside the card holder is a size reference and not included. Both sides are Louis Vuitton canvas, on side is crafted align with the original logo. 6 slots plus one center slot for cash or anything can fit.
