Has anyone ever figured out the 10th Doctor's Wallet

[The Next Doctor]

I know that there is the one with CO Sonic Screwdriver, but I was curious if anyone knew the correct size or manufacturer for the real wallet. I am assuming that it is a basic ID wallet. Are UK Drivers Licenses/ID's the same size as their US counterparts?

the one that comes with the Screwdriver is really actually perfect
