Credit card sized in 1.2mm thick stainless steel, this spanner set fits neatly in your wallet with metric sizes M5 to M14.
This wallet essential is incredibly useful for an impromptu spot of DIY. If MacGyver hadn't been fired by the Phoenix Foundation for mullet-abuse, he'd have one of these, right next to his Swiss Army Knife.
Changing the car battery, fixing the brakes on your bike, or knocking up a makeshift tank in the warehouse you've been unexpectedly imprisoned in; you know it'll come in handy.
