Crafted from durable paper cloth with a cotton blend, this Traveler's Factory insert transforms your passport-sized notebook into a functional storage system. The compact design (H125 x W95 x D10mm when folded) slides seamlessly into standard leather covers and features three dedicated pockets: a zippered compartment for coins and keys, a card slot for business cards or credit cards, and an envelope-style flap pocket for receipts and tickets. Japanese-made quality built to last.
