It is basically a tool kit that covers all things on-road both metric and standard. Your friend who isn't using a 2mm wrench is probably using a 5/64". It is likely his 2mm is somewhat worn out and fits loosely now. The AE wrenches are good but pretty soft and they do wear out. And actually if you look at the bit for their newest set, part #1659, they list it as both a 5/64" and a 2mm wrench. Its a metric car...you'll need metric tools.
