I purchased this item and used it for several years before storing it at home for a long time. It's an old item, but my family recently tried it out and confirmed that it's in good working condition, so I'm offering it for sale. The total weight of the rings is 15kg. The breakdown is: ★1.25kg x 4 plates ★2.5kg x 4 plates Shipping will be via Rakuraku Takkyubin. The total weight will be quite heavy, around 20kg. Please be aware of the above before purchasing.
