MMF Industries Steelmaster Locking Heavy-Duty Security Box

The MMF Industries Steelmaster Locking Heavy-Duty Security Box can help you efficiently store your valuables. This security safe is resistant to impacts, and can withstand collisions. It is resistant to scratches, accidental nicks, and scuffs.

The Steelmaster Locking Heavy-Duty Security Box by MMF Industries is built from high-quality stainless steel, which makes it last for a long time. This security safe has a pin tumbler lock at the front that serves as the only means to access its contents. A continuous hinge makes this security safe sturdy and robust. Important documents, family heirlooms, antiques, USB pen drives, USB hard disks, and other personal effects can be placed inside this security safe. A powder coating finish serves to make it durable. Lightweight and portable, this security safe can be placed in suitcases to conveniently carry different types of valuables and personal effects. This security safe, with a nickel chrome finish, comes with two pin tumbler keys that facilitate use even if one key is unavailable.

Easy to care for, this safe can be wiped clean with a soft and dry cloth to ensure that it looks as good as new for a long time. This helps maintain its original appearance for years to come.
