FIELDOOR adjustable dumbbells. I am selling these as they are no longer needed in my home. - Shafts: 2.0kg x 2 - Plates: 2.5kg x 4 - Plates: 1.25kg x 4 - Stoppers: 0.25kg x 4 - Connecting shaft: 1.3kg x 1 You can make two 10kg dumbbells with both hands. You can make a maximum of 18kg dumbbell with one hand. It can also be used as a barbell when connected, but I haven't used it that way.
