Thank you for viewing. Due to the high number of views, I'm offering a special, limited-time discount until around 8 PM on October 18th. Please take a look! This is a SLIK SBH-320 ball head. The ball moves smoothly and can be securely locked. Please assess the appearance from the images, but there are some scratches and dirt from use. I'm selling this because I no longer need it after changing my tripod head. Also, a third-party screw adapter is included. How about it? Please consider it.
