I am selling this item because it is no longer needed as my child has grown. I used it for about a month after my child was born. After use, I dried it well. The photos show the item with the air removed. There are no air leaks. A pump is built-in, so you don't need a commercially available air pump to inflate it! I have disinfected it with alcohol and stored it at home, but please understand that this is a used item. Manufacturer's suggested retail price: 4400 yen
