Purple exercise hula hoop with a counting function. - Color: Purple - Accessories: With counting function - Parts: Removable parts - Function: Exercise hula hoop Thank you for viewing. I'm happy to sell it. Immediate purchase is OK. It's an exercise hula hoop. It's the type you swing around your waist, like filling a water bottle. The length can be shortened by removing parts. It also counts how many times you've swung it. Recommended for those who want a slimmer waist! Thank you.
