MSTRMND Collective has an upcoming product called the MSTR LINX titanium carabiner key ring set that has a clever quick-release mechanism for swapping sets of keys with ease. The rings are machined from a solid plate of Grade 5 Titanium, and they each have a special notch that allows them to pass through one another when positioned perpendicularly.

This video shows how it works:

That key-swapping action takes some precision to get right, so you don’t have to worry about the rings coming undone in your pocket or from your belt loop. The 6-piece set comes with one carabiner (which doubles as a bottle opener with the “gate” pushed in), two MINI LINX rings, and three key rings.

Following their very successful Kickstarter campaign, MSTRMND Collective is gearing up to start shipping the MSTR LINX set by August 31st, 2018. Pre-order it for $75.
