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 new price on Amazon is about 11,000 yen, so this is a great deal. It was only temporarily installed and never actually used, so it's in like-new condition. All original components are included: the plastic fixing parts, handrail, toilet seat itself, and the instruction manual. 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
