I am selling a toilet seat purchased in December for an elderly family member. We did a temporary installation, but due to space issues, we were unable to use it. The item is in like-new condition, having only been temporarily installed. The original price on Amazon was approximately 11,000 yen, so this is a great deal. All original components are included: the plastic fixing parts, handrail, toilet seat, instruction manual, and everything else that came with the purchase. The compatible sizes are as shown in the images. Please refer to the Amazon product page below for more information: https://www.amazon.co.jp/dp/B0987MCWYZ?ref=ppx_yo2ov_dt_b_fed_asin_title
