BODY DESIGN 28mm Diameter Dumbbell Shafts - Set of 2, with Collars - Price includes shipping. The knurling is in very clean condition with no rust. *Please rest assured that there is no knurling paint to hide rust, which is often seen in other used items. Length: Approximately 40cm Compared to IROTEC, the knurling is more pronounced, making it less likely to slip even with heavy weights. Will be shipped in simple packaging with cushioning material only. I also list many high-quality training equipment items frequently, so please follow my account and check out my other listings.
