[Double Supervision by Former Police Officer and Security Equipment Specialist] Developed jointly by a former detective who has witnessed numerous intrusions and security experts. Based on data recommended by the National Police Agency that "approximately 70% of intruders give up if it takes 5 minutes to break in," this is a professional-grade security key box that builds a "5-minute barrier" to protect your keys from unauthorized picking and destruction.
[Overwhelming Toughness Compliant with US Military MIL Standards] The main body uses "high-durability, impact-resistant ABS material" that disperses and absorbs shock. It has passed 26 drop tests from a height of 1.2m at a domestic testing institution, demonstrating reliable durability without cracks or damage. It overcomes the weaknesses of iron boxes, such as "rust, weight, and deformation at high temperatures," making it ideal for harsh outdoor use.
[Uncuttable! Extra-Thick, Hardened Steel Hook] The hook part, which is most vulnerable to attack, uses high-density, robust "hardened steel" (12mm in thickness). Unlike conventional wire hooks, it achieves overwhelming strength that withstands hammer blows and cutting tools such as wire cutters. It completely eliminates the risk of someone stealing your important spare keys.
[10,000 Combination Codes & Convenient 2-Way Installation Design] The 4-digit dial allows you to set 10,000 different combination codes. It also features a sliding splash-proof cover to protect the dial from rain and dust. It's a 2-way design that supports not only easy "hanging on a doorknob" but also "wall mounting" using the included hardware. It is suitable for various installation environments such as sharing spare keys at home, offices, shops, and short-term rentals. (Large capacity design that can store up to 7 keys)
[Full-Color Instruction Manual Packed with Security Know-how ] In addition to easy-to-understand operating procedures, a dedicated instruction manual is included that features "correct usage to enhance security" and "useful security columns for everyday life," supervised by a former police officer.
