This is a genuine Ichijo Homes thermal insulation bathtub lid. Size: Approximately 72.5cm x 72.5cm x 3cm Used from 2010 to the end of 2025. While it still provides insulation, it's heavy, so I replaced it. There is wear and tear commensurate with age, including dirt, deterioration, and cracks/damage around the edges. (Please imagine the rest from the areas shown in the photos, though not everything is pictured.) Due to its size, the packaging and shipping costs are high, hence the price. This item will be listed until the next "non-burnable trash" or "bulky waste" collection day. Thank you.
