This is a set of 3 washable pet sheets. The first and second sheets from the left are regular size, and the third sheet from the right is half size, so they can be used for small to medium-sized dogs. The first sheet from the left is a thin sheet. The second and third sheets are quilted mats, 1mm thick, and have high absorbency. I received these as used items, but I haven't had a chance to use them and have been storing them. They have been washed, and there is no odor. However, the first sheet from the left has some black spots. They are not mold. They do not affect use, so it's a great deal for those who don't mind. Perfect for those who want to buy them a little cheaper. [Contents] From left to right: ① 62x45cm ② 67x45cm ③ 43x30cm [Accessories] None [Shipping Method] Yu-Yu Mercari Delivery
