Mühlen Secret Safe 240 — Book-Shaped Hidden Safe Disguised as an English Dictionary

Who Is It For?

Mühlen Secret Safe 240 is a book-shaped hidden safe for people who would rather keep cash, jewellery and important papers out of sight than lock them in an obvious box. Designed to look like a large English dictionary, it sits among the other books on a shelf without drawing attention. That makes it practical at home, in the office, in a student room or in rented accommodation, and a sensible choice for anyone buying a concealed safe for the first time.

Key Features and What They Do

  • Dictionary camouflage: On a bookshelf it blends in completely; when nobody realises it is a safe, the risk of it being opened or taken drops considerably.
  • Steel inner chamber, hinge and lid: The metal interior resists impacts and unauthorised use.
  • Strong ABS outer shell: Durable material that gives the book exterior a long service life.
  • Changeable combination: A 3-digit lock from 000 to 999 means no key to carry or lose.
  • Generous size: At 24×15.5×5.5 cm, the large format leaves room for banknotes, jewellery and folded documents.

Frequently Asked Questions

Can I change the combination myself?
Yes. Any combination between 000 and 999 can be set and changed by the user.

Is the safe really made of steel?
The inner chamber, hinge and lid are steel; the outer shell is strong ABS.

Do I need a key?
No. It opens and closes with the combination only.

How large and heavy is it?
It measures 240x155x55 mm and weighs 0.8 kg net.

Usage and Care Tips

Place the safe between other books in a spot that does not stand out, so the camouflage does its job. On first use, replace the combination with a personal one and keep a note of it somewhere safe and separate. Keep it away from very humid places and avoid heavy knocks to protect the steel chamber and the lock mechanism. It is covered by a full 24-month warranty against manufacturing and production defects.
