Thank you for viewing. This is the TF-19U1 pet thermometer. I used it about twice, but I no longer need it, so I am selling it. The tip is flexible, and it's designed to be safe for pets. It has a backlight function, so you can use it safely in the dark. The main unit, outer box, instruction manual, and 23 dedicated covers are included. Operation has been confirmed. A test battery is also included. When shipping, I will flatten the outer box and seal the main unit in a Ziploc bag. This is being sold as a used item. Since I am a private seller, there may be oversights. Please understand. Immediate purchase is welcome. Thank you.
