I've been wearing my wallet on a chain for over three decades. When I started having concerns about leaving my phone behind while riding public transportation, I didn't like the look of the lanyards and straps available to keep track of my phone. The logical option was to find a way to attach my phone to a chain the same way my wallet was attached. 22-inch chain. Long enough that most people can talk on their phones without detaching the chain from their beltloop. Long enough for everyone who uses Bluetooth or a wired headset. Security knowing that you can't lay down your phone & walk away from it. Easy way to locate your phone when you don't know which pocket it's in - just follow the chain. Spring-loaded carbiner for easy attaching/detaching. Spring-loaded ring clip for each attaching of keys, pocket watch or other accessories. Durable plastic clip works with Android or iPhone cases. Small enough that you can charge your phone without removing the clip.
