Thank you for viewing. These are dumbbells made by iROTEC. Although there is some wear and tear, they are in good condition as they haven't been used very often. Due to weight restrictions for shipping, please purchase both sets: 【Set A】 and 【Set B】 (totaling 40kg), 20kg each. The price is 6,000 yen x 2 sets = 12,000 yen. I am also selling 【Set A】 separately, so please check it out. If you purchase a single set, the transaction will be canceled. Please refrain from bidding if you are in Hokkaido, Okinawa, or other remote islands due to shipping costs. 【Product Contents: Total of Sets A and B】 - Brand: iROTEC - Weight Plates: 1.25kg x 4, 2.5kg x 4, 5kg x 4 (Total of 12 plates) - Shaft with collars 2.5kg x 2
