Meet my new unpickable lock! Our new dedicated BRAY in FILT technology has removed free space in lock, and ultimate picking detection method detects any picking tries, and when it's detected, it PERMANENTLY locks the lock, making it unable to open contents without brute-force attack. Always use the right key to open lock!
