This clever key-swapping system definitely feels like the future

MSTR’s Linx ensures that interchanging keys between keychains will never be a headache again. Linx’s rather creative key-swapping approach isn’t time-consuming, requiring you to slide out a key by wedging your thumbnail into the keyring and rotating the key for minutes before it comes out, only to repeat the process, in reverse, for putting the key back in. Relying on a system that uses positive and negative shapes (think: jigsaw puzzle, or key and keyhole), Linx allows you to simply slide the keyring in and out of its holder by matching shapes (seen below), and sliding the keyring in or out in a manner that’s just extremely soothing to look at!

The Linx quick release system comes made in titanium, letting it have a usage cycle that probably runs for centuries, never wearing out, and providing perfectly microscopic tolerances and a smooth sliding action every single time. Available in three models, the Mini Linx connects to your keys, and slides into the Medium Linx or the Carabiner Linx, ready to be strung, hung, or just stored in your pocket. Sliding the keys in or out takes mere seconds, and can be only done through concentrated human participation. Its design, construction, and tolerance mean your keyrings will literally never slide out by accident… and swapping keys is a literal breeze!
