The safe is made of steel and features 3 security bars and a special bar-type hinge for enhanced protection against tampering attempts. The carpet inside protects your items from scratches. Additionally, the primary component of the insulation is cement with special additives that "trap" millions of water molecules. In the event of a fire, these molecules boil and create a shield of steam that keeps the interior of the safe below 121°C and can protect valuable items and documents from fire for 60 minutes.
