Thank you for viewing. This is a K Zildjian Custom Medium Ride 20 inch (the stamp font of "custommediumride" seems to be slightly different depending on the year or perhaps a whim). Approximately 2,600g (approximate weight). No cracks, hole is OK. The front has both lathing and shallow, fine hammering (photo ★ is not stick marks). The back is an intact specification without lathing (some polishing by the manufacturer). I have used it only for test strikes. The IE number of the manufacturer's logo engraving can be read. It has a delicate and sharp stick sound that doesn't get out of control. Please consider it if you are interested.
