This is a PROIRON diet hula hoop. I've used it about 10 times, but the material is prone to scratches, so there are scratches and what appear to be red stains overall. It works fine for hula hooping, but it's not in perfect condition, so please refrain from purchasing if you are concerned. It's detachable, with 6-8 sections (maximum diameter 98 cm), allowing you to adjust the size and weight. How about using it for weight loss after the New Year's holidays or for the summer? It will be disassembled and shipped in a dedicated bag.
