If you have an obnoxiously loud bike, this keychain is for you! However be warned, your ridding buddies will be jealous when they see you with this key tag.
This keychain doesn't just look awesome, it's also extremely useful. At 5.11" (13cm) it's nice and big, making it easy to pull from your pocket - even with gloves on. The size also makes your key much harder to lose and easier to find when you do lose it!
