Hasa Mammoth Z Front and Back Set for Rental Use, 180cm, 3 Sets, Finger Pinch Prevention Three sets of 180cm front and back pieces. Currently sells for 17,000 yen on Rakuten. I bought these about a year ago for my child, but I haven't used them because they're troublesome to install, so I'm selling them. As shown in the photos, they will be sent in the same condition as when purchased.
