Harbour Card Holder

Made this for my parents boat, to hold harbour cards. (cards you use to pay for showers and electricity in harbours) Holds eight seperate cards as well as having a large slot on top for guestcards, which are just cards with no money on, but allows entry to the bathrooms. Also uploaded versions with 1, 2, 3, 4, 5, 6 and 7 slots.
