This is a duck-shaped digital water thermometer. Thank you for viewing. I used it a few times when my child was born and then stored it away♪ It can be used for small baby baths or even after they've graduated. I have fond memories of enjoying bath time. Operation has been confirmed. Please understand that there are no instructions. How about it for preparing for childbirth❓ Batteries are not included. - Design: Duck-shaped - Color: Yellow - Features: Digital display Thank you for viewing.
