This is a baby bath thermometer from Akachan Honpo. It's a slim thermometer with a temperature range of 0-60°C. It's convenient for measuring the ideal bath temperature for your baby. I haven't used it in a while (about 2 years), but I've tested it by putting it in hot water and confirmed that it works.
