Are you tired of pulling out your keys at work every time you walk in and out the door? Well, I have a solution for you (if it requires the rfid / NFC key) it’s a handy wrist mounted holder for the key. All you need to do is print it!
Now, aside with my salesmanship lets get to the specifications: this wrist holder will accept watchbands up to 26mm and the thickness of 2mm. I recommend a nylon watch band (Yes the nato one) its made for the 26mm but 24mm or 22mm should work fine all thought it won't look / fit so good. Of course you are free to change the size of the holes.
