Thank you for viewing. These are beautiful chrome-plated dumbbells. They are not cheap, large-shelled cement ones. Total 20kg (2.5kg x 6, 1.5kg x 2, shaft = 2kg), with some rust. No box. Shaft diameter: 25mm Shaft length: 400mm Manufacturer: Yamazen I am selling them at a low price, so I cannot offer a discount. I will ship via Yu-Yu Mercari Delivery (anonymous shipping). The maximum shipping weight is 25kg, so I cannot ship two sets together.
