This is a set of a kettlebell shaft and two plate stoppers. You can adjust the weight to your liking by attaching dumbbell plates! The black part at the bottom has a reverse thread, so you don't have to worry about the weight coming off. (However, please attach it correctly. We cannot guarantee that it will not come off completely.) There is some wear and tear. Please check the photos. Length: Approximately 40cm Weight: Approximately 3.2kg (bar only)
