Tired of prying open old school key rings and destroying your finger nails? Just squeeze the FREEKey and slide em on! This is one of the coolest innovations to a product ever. We don't make them (Exotac does) but I've used a FREEKey for a couple of years and when I designed the Metal Shop Mini Pop opener I knew I wanted to use the FREEKey as the key ring. The Basic is just a single, simple to use FREEKey. Try it! You'll never go back.
