The Fisher Bullet Pens fit perfectly in your pocket or jacket but they also fit perfectly inside a wallet. All seams of the Fisher Space Pen wallet are folded and double-stitched providing years of faithful service. The wallet is a bi-fold and contains 7 slits for credit cards which can be doubled to hold over 14 credit cards. Behind the credit cards are two inside pockets to hold business cards. The Matte Black Bullet Space Pen sits in its own custom made pouch, right between the two credit card panels.
