Purchased on Amazon for ¥3400. Used once, but my pet suddenly refused to use it after we changed the toilet, so I'm selling it. It has been cleaned. There are no smokers in the household. It's used by attaching the round pad holder to the wall. Please see the actual images from the 6th photo onwards. Please note that it will be folded for shipping to reduce shipping costs. Silicone pad holder, perfect for dog toilet training. - Brand: BaraRose - Size: Approximately 89X65CM - Product Size: 650mm(25.5in) x 890mm(35.1in) x 300mm(11.8in) / 400mm(15.75in) - Application: Pet training pad holder Thank you for looking.
