The indicator function shows if the TSA/ HMRC special tool has been used to open your lock: Red - Special tool used and Green - Lock has not been opened by TSA/ HMRC. The US Travel Security Agency (TSA) and Her Majesty’s Revenues and Customs (HMRC) maintain the right to open any case, even if it is locked. Therefore they can cut off your normal lock, destroying it forever. Korjo Travel Sentry Lock solves this problem – because you can now lock your case again without worrying that it will be destroyed by the TSA/HMRC. Set your own combination (instructions enclosed). Authorised TSA/ HMRC agents can use a secured tool to open the lock, check your case and relock it. The pack contains 2 black locks and 2 black keys.
