Economical
In addition to its functional features, this model is offered at an extremely economical price, whether for personal use or as a gift for children.
Strong Metal Interior Case
The model has a metal inner chamber and lid, while its outer shell is made of ABS material. Sufficiently resistant to external interference, the model prevents unauthorized use.
Strong Lock, Double Keys
The MÜHLEN Secret Safe 115 model, with its double keys, prevents unauthorized use thanks to its strong lock. Designed to serve for many years, the MÜHLEN Secret Safe 115 has a lock system for opening and closing the hidden inner chamber, meaning the lock itself is not visible from outside.

Fully Camouflaged Hidden Safe
Shaped like an English dictionary, the MÜHLEN Secret Safe 115 is fully camouflaged and goes unnoticed by others. This way, it stays completely hidden from strangers and unauthorized users, and its steel inner chamber provides extra protection beyond the strong lock.

Mühlen Secret Safe 115 — Mini Book-Shaped Hidden Safe and Piggy Bank
Who Is It For?
The Mühlen Secret Safe 115 is a mini hidden safe disguised as an English dictionary, for anyone who wants to keep some cash, a spare key or small keepsakes out of sight without investing in a heavy steel cabinet. It suits student rooms, shared flats and offices with petty cash, and with its slot for bills and coins it also works as a piggy bank, making it a thoughtful gift for children who are learning to save. Its protection comes from camouflage combined with a metal inner chamber and a concealed lock.
Key Features and What They Do
- Dictionary camouflage: On a shelf among real books it goes unnoticed, which is the first line of defence against strangers and unauthorised users.
- Metal inner chamber, lid and hinge: Beneath the ABS outer shell sits a metal structure that adds physical protection to the disguise.
- Dual-key lock, invisible from outside: The strong lock opens with two keys, and because it cannot be seen, nothing gives the safe away.
- Bill and coin slot: Add money without opening the lid, so it saves like a piggy bank and stores like a safe.
- Mini format: At 115x80x45mm and 250 g it fits easily in a drawer or bookcase and is simple to move.

Usage and Care Tips
Because its strength lies in staying unnoticed, place it between real books rather than on its own in a visible spot. Keep one of the two keys in a separate safe place as a backup. Use the slot for everyday saving and the inner chamber for small valuables. Wipe the ABS shell with a dry or slightly damp cloth and avoid chemical or abrasive cleaners. Remember that this is a hidden safe rather than a heavy steel cabinet, so discretion is the key to using it well.
