MÜHLEN Secret Safe 240-P — Hidden Combination Safe in Book Design
Who Is It For?
MÜHLEN Secret Safe 240-P is a hidden combination safe for anyone who wants to keep cash and small valuables out of view without installing a heavy steel cabinet. Its large book format goes unnoticed on a shelf at home, in an office, a dormitory or on a study desk. Here the main protection comes from concealment: a visible safe attracts attention, a book on a shelf does not.
Key Features and What They Do
- Book-style look: The large book-style body sits naturally in a bookcase, so a thief may not even realise a safe is there.
- 3-stage combination lock: Combinations from 000 to 999 that you can reset whenever you like, with no key needed.
- Metal interior: The steel inner chamber, hinge and lid resist impacts and attempts at unauthorised opening.
- ABS exterior: The outer shell is made of strong ABS for a realistic yet sturdy finish.
- Light and easy to reposition: At 800 g it can be moved between shelves whenever you rearrange them.

Usage and Care Tips
After opening it with the factory setting, change the combination to your own code between 000 and 999 and write it down outside the safe. Placing it among books of similar size, away from eye level, improves concealment. Keep it out of damp areas to protect the steel chamber and hinge, wipe the ABS surface with a damp cloth and avoid solvent-based cleaners.
