It's a commonly used movie trope: hiding something important or valuable in a hollowed-out book. It's a trope because it's effective, and Puebco has done the work for you with this stash book. Varied faux covers are available, with each one offering an internal space large enough to store anything that might otherwise end up in a valet tray, including cash, cards, correspondence, SD cards, watches, and other valuable EDC-sized items.
