Some people find it hard to remember the number combination of their lock.  Wordlock uses letters instead of numbers.
The US Travel Security Agency (TSA) and Her Majesty&rsquos 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. The 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
