Inside the books, you’ll find 60# Finch Opaque White with light gray dot-graph, perfect for reconnaissance diagrams or snippets of secret code. The last page of each book features a three-part history of codes and ciphers with many examples and anecdotes. There’s also handy cross-reference matrix of various codes on the back covers, because you never know when you’ll need to crack something.

On the surface, it’s every bit as attractive and useful as any of our notebooks. But there’s quite a bit more to this 3-Pack, and as much as we want to tell you about it, we’re bound to secrecy for now.

Agent identification card, and (whispering now…) preparing you and your fellow agents for a bigger mission outside the books.
