This clever key-swapping system definitely feels like the future - Yanko Design
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. 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.
