Today in the Sunday Times and several other UK Newspapers are running a recall ad from Ikea. The Allen Key is a small iconic IKEA product made from highly-recyclable material useful for re-adjusting Ikea furniture long after it's been assembled. Sadly, Ikea did not notice that they have handed out left-handed Allen Key's to all customers, including right handed ones, all of 2012 thus far. They'll be happy to exchange the Allen Key for you if you go to your nearest Ikea store with your "wrong" key.
