The London Underground is a great way to avoid getting stuck in traffic and move around the city, but even people who use the Tube on a regular basis will admit to getting confused with all the stations and different lines to choose from.
Avoiding this problem the next time you travel can be solved by simply buying one of these credit card pocket sized maps.
This really would make the perfect gift for anyone who visits / works in London. Made from stainless steel, the pocket Underground Map card is super strong and will last forever. This could prove to be one of these little gifts that come in handy when you least expect.
