This is the hot air belt, an optional accessory for the Pelvic Stretch Chair Plim up EX. I forgot about this when I got rid of the chair and it's been stored in the closet. I think it's in good condition because I hardly used it and it was kept in the closet. Since I don't have the main unit, I can't confirm that it works. I'm starting the price at this level in case it doesn't work (if it doesn't work, please have it repaired by the manufacturer yourself.) - Model Name: Plim up EX - Color: White - Included: Power cable - Material: PU leather Thank you for looking. This item is a stretching device.
