This is a baby thermometer that you use under the arm. It's small and convenient to carry, and it's quick and easy to take a temperature. It's currently discontinued and a rare item that's hard to find. It has been stored in a dark place for a long time after use. There are fine scratches on the case and the LCD screen of the main unit, but the other parts are in a clean condition without any noticeable dirt or scratches. Also, the battery display is clear, so I think it will last for a while, but I don't know how much is left. It is recommended for those who can replace the battery themselves or who don't mind if the battery is low. Please understand that this is stored by a private individual and has been stored for a long time before purchasing. [Size (approx.)] 5cm long x 4cm wide x 2cm thick
