For too long your keys have made you sound like a janitor or a prison guard when you walk around. It’s time to put damper on the audio of your approach. MAGKEY is a set of N42 neodymium magnets that stick to your keys to keep them from sounding like Christmas bells while you move around. Each magnet is under a 1mm thick, weighs less than a gram, and is waterproof and rustproof. Stick them to your keys and your ninja game will be back intact. Sometimes the simplest ideas are the most brilliant ones.
