The Fisher Space Pen wallet is a bi-fold and contains 8 slits for credit cards which can be doubled to hold over 16 credit card . Behind the credit cards are two inside pockets to hold business cards or stash that extra $20 bill . There are two generous currency slits that are deep and VERY generous to accomadate separate foreign currencies ; or to store your receipts. Personally , i like this deep currency feature because it keeps your bills private and deep i your wallet , away from "prying eyes ". Last but certainly not least is the authetic Nickel Plated Chrome (or Black Matt) Fisher Bullet Space Pen that sits in it's own custom made pouch , right between the two credit card panels . You'll always be "packin your bullet" and ready to write . The Fisher Space Bullet IS INCLUDED for free with this deluxe wallet .
