This item became unnecessary after the lighting was replaced in early January 2023 (Reiwa 5). It was used for about 20 years in a washroom (approximately 3 tatami mats in size). The dimensions are approximately 40cm x 75cm x 9cm. There are no noticeable scratches or stains, but the frame is yellowed. It was working properly until it was replaced. I am not good with electrical things and don't understand them well, but it is a direct mount to the ceiling. The parts shown in the images are all that are included, and I cannot tell if anything is missing. I felt it would be a waste to just throw it away, so I am listing it in the hope that someone can use it. It is scheduled to be shipped as a 140-size package via Rakuraku Mercari Bin, but I can change it if you have any preferences.
