This spray can be used to keep the water warm for washing a baby's bottom. Use it by putting water in a spray bottle. (For hygiene reasons, the spray bottle is not included. You can buy one at a 100-yen shop like Daiso. The one in the photo was purchased at Daiso.) It has a warming function, so you can always wash with warm water at 30-40 degrees Celsius, keeping it clean. I think it will be especially useful in the cold season. Box not included. ・Size: Approximately 20cm high x 15cm wide ・Capacity: 300ml
