First of all, if you are looking for an ID to get u into clubs in the UK, u should know that novelty id are traceable, anybody can check if they r valid or not, not to mention the fact that most of them can be spotted as novelty in an instant. Secondly, you're approaching the problem the wrong way. First, you need to look OLDER than your age. Secondly, you don't need a UK id that can be checked in an second in a database; you need a foreign id, pass or driving license, because nobody will be able to check it. Every country has a database, that is private. So instead of getting an English novelty, try an Eastern-European (their databases aren't integrated into the Eu yet) , Israeli, Australian id, pass or DL. Thirdly, the novelties from the mentioned countries have souvenir written on them in the native language, so nobody knows it says "souvenir", but also, you cannot be charged by any institution with using a fake.
If you need more info or want such a novelty, just email souvenireuid at yahoo.co.uk or same nickname at gmail.
