I purchased this at Toys "R" Us last year for 4999 yen and used it for one month. It's in very good condition, and I hate to throw it away, so I'm offering it for sale. A hole about 0.5mm wide appeared shortly after purchase, but I used strong adhesive tape that is resistant to water droplets to cover it. There are no air leaks. The transparent tape is not noticeable. Please check the fourth photo. The hand pump and instruction manual are not included. Target age: 0 months and up Thank you for looking.
