Electric heater to keep your pet comfortable with two temperature settings. I bought it for my dog, but I've been storing it without ever using it. I'm selling it because I have no opportunity to use it.＾＾ There is no box. I checked the operation and it worked fine. - Brand: Petio - Size: Approximately 37cm x Approximately 26cm x Approximately 3cm - Temperature settings: Approximately 39°C (High) / Approximately 32°C (Low) - Type: Electric heater - Version: ver.2.0 Thank you for looking.
