I've used this for about two years. I'm selling it because I've gotten rid of my bike. It shows signs of use, but it's still practical and can be used extensively. There are some scratches on the resin part of the chain lock. There are three keys. (One of the keys I used is slightly bent) I checked Amazon, and a new one of the same item is about 4300 yen.
