This is athlete2 from MTG Style. I purchased it in September 2025 from the official MTG shop on Rakuten for 16,280 yen. I used it in the office to prevent lower back pain. I'm selling it because I don't have much opportunity to use it. I think it's in a clean condition with no noticeable stains. Please check the images. If there are any areas you're concerned about, I can take additional photos, so please let me know. Please check the 15th image for the size and materials. I will include the official packaging plastic bag, shop card, warranty (1 year warranty), and delivery note. *This does not necessarily guarantee free repairs.
