These are disposable diapers for extra-small dogs and cats, suitable for 1.5kg to 3.5kg. I opened the package and used three diapers, but then my pet passed away. They are stored clean. To keep the price down, I will repackage them in a ziplock bag and compress them for shipping, using gloves to keep them clean. The tail hole is adjustable. The abdominal tape can be reapplied and still sticks well. There are two cute designs, and it was adorable to see my pet wearing them. I hope they can be used by another cat or dog before being discarded.
