Thank you for viewing. This is a 2.72kg (for junior high school girls) shot put for track and field. It has not been certified, so it cannot be used in official competitions, but it is made by Nishi Sports, so there is no doubt about its quality. - Weight: 2.72kg - Model: Shot put - Packaging: Boxed This product will likely only interest those involved in the sport, but how about it for those working hard at track and field?
