Now here's a nifty idea from the people who brought you the credit card sized spanner. The credit card sized plectrum - three of them, in fact, precision etched into a shiny stainless steel card 0.25mm thick. The card itself measures just 85mm x 54mm, meaning it can take pride of place in your wallet with your far less desirable bank and loyalty cards. We think these are simply the perfect gift for the perfectly gifted musician. And who's to argue with that. So when Mark Knopfler pops round for a quick jam session with Sting, you just need to get on down and reach for your wallet. Not to write a large cheque, of course, but to reach for your wallet essential. Then it's off to the mosh pit, as we believe it's called, for some uncoordinated flailing around to your own version of Sultans of Swing. Simply rockin'.

This Wallet Essential comes from a range of such tools from the cutting-edge design gurus at Touch of Ginger (although whether this is an indication of the disproportionate genius of redheads is unclear). Whatever the root of their name, one simply cannot question their design credentials - and these steely plectrums live up to their creators' reputation. Small. Perfectly formed. And brilliantly functional.
