Thank you for viewing. This is a used item. KBPT (kouboupath) Material: Oak color [Thick cotton material] Leather: Brown Pin diameter: 8mm I used this for about a month, but I am selling it because I replaced it with another one. There are marks from attaching it to a guitar, as well as scratches and rust on the metal. Please see the photos. The serial number was written in magic marker from the time of purchase.
