The Mossad Pen is a breakthrough in covert-ink technology that lets you convert ordinary handwriting into a temporarily non-visible, secure format — then restore it when needed. Using an advanced gel formulation, the black ink becomes invisible with gentle heat (a hair dryer) and reappears after cold storage (a freezer). The process is reversible and repeatable, making this pen ideal for discreet note-taking, secure transport of sensitive information, and private record-keeping where low-profile concealment is needed.
Engineered for smooth, low-pressure writing to minimize telltale indentations, the Mossad Pen features a comfortable ergonomic body and a 0.7mm fine point for precise lines. Refill cartridges are available so you can reuse the pen indefinitely.
