This is a LEAD BEE LOCK shackle lock. I bought it new in August of this year and used it only once. However, I found it troublesome to remove it every time I rode, so I stored it indoors without using it further. There are no issues with its operation, but there are some minor scratches and signs of use, so please refrain from purchasing if you are overly concerned about these details. *I have set the price to the minimum, so purchase is on a first-come, first-served basis. Thank you.
