I wasn't 100% sure what this was for when I purchased for my husband. Once I got it, gifted it to him and he got excited, I realized I'd done a good thing. Lol his keys for work are all together, he doesn't have to dig in his pocket anymore and he's pretty happy about it! The functionality of it is amazing, not to mention the look of it is gorgeous!
Great piece of EDC gear!! It keeps my keys organized (four keys and a key chain token), allows for you to tailor its size, and comes with a pocket clip that you can add to it, if wanted. Keys are easy to get to, but not not loose and getting tangled with other pocket "litter".
