タイトルまたは説明

The first ever possible lock in the world! It's safer than the safe. Secure it for a secured life! Nobody will know your secret codes even they are standing behind you, watching you pressing the pin numbers. Simply press some dummy numbers at the beginning, then the real pin codes, followed by some dummy numbers again at the end. Your real secret is embedded somewhere in between and nobody can ever know when you start or end. User needs to press 6 digits out of *2 in sequence to make the lock open and such combination accumulates up to **5,**0 possibilities! It's unique and no other combination locks can achieve this function, neither the bank's pin machine nor any electronic combination lock. No worry of electronic problems as the lock is fully mechanical. It works in all weather situations, high or low temperature, key or keyless option.
