Product Name: Iris Ohyama Sheet Pitatto Tray Double Wide P-SPTD White Size: 63cm (length), 88cm (width), 2.7cm (height) (Double Wide) Material: Polypropylene * This is a large double-wide toilet tray from Iris Ohyama. I purchased it about 3 years ago and used it when my puppy was young, but I removed it and stored it when he became an adult because the size was too small. Before packing, I washed it thoroughly with a bathroom cleaner and sponge, and then dried it in the sun. * Due to aging, the plastic has deteriorated, and the center part is curved, as if it's bulging. * When using two wide sheets, urine may leak onto the floor from the joint of the tray when the dog urinates in the center, so I recommend using one double-wide sheet. * The adhesive part loses its stickiness over time due to dust, but it can be restored by washing it with a cleaner and sponge and drying it with a shower.
