◆ Set of 20 sheets Thin Pet Sheets ・Regular (33cm x 45cm) I was using these as changing sheets for my child, but they are no longer needed now that they can stand, so I am selling the extras. (Due to shipping costs, I'm selling them in sets of 20, but I have 100 sheets... If you need more, please contact me with the amount and we can discuss the price.) This size is suitable for babies from 0 to 1 year old. For pets, this is a size suitable for toy poodles, Chihuahuas, and other extra-small dogs.
