Build Your Own Mechanical Safe with a Secret Combination

What if you could build your own safe from scratch and then unlock it using a secret combination of your choice?

Made up of 420 pieces, this clever model features a working combination lock, a rotating handle, an opening door and a compartment for storing coins.

Explore the Gears and Discover How the Lock Works

One of the most interesting features of Safe Too is its visible mechanical construction. Open the door and you can see the gears and levers working together to operate the locking system. The combination of natural wood, mechanical details and rich brown and red accents gives the model the appearance of a miniature vault, while retaining the distinctive charm of a UGEARS wooden mechanical puzzle.

There is another clever detail to discover. A coin slot at the top allows coins to enter a visible track along the side of the safe before dropping into the storage compartment at the bottom. This feature adds an extra layer of interaction, making Safe Too both a mechanical puzzle and a fun place to keep small savings. Watching the coins travel through the mechanism is part of what makes this model so enjoyable.
