A fin key key chain. I got tired of always diving into cup holders on the boat or digging through my surf bag to find my fin key. So i came up with this clip on clip off style keychain key so i could clip onto my boat keys, my car keys, and my surf bags. I use them all the time. I figured someone else out there might appreciate it as well.
