This is a Swimava neck ring. It is an authentic, regular size. Used only a few times when my child was small. Since it has been used so few times, it is in overall good condition. There are no air leaks, and it can be used without any problems. After each use, it was washed, dried, and carefully stored at home. It comes with the box and instruction manual, and everything in the photos is included. *Please refrain from purchasing if you are concerned about minor details, as this is a used item. How about it for bath time or baby swimming? Please feel free to comment if you have any questions. Instant purchase is OK.
