Marukan Heat Ceramic - Model: Heat Ceramic 40W - Size: W76 x D76 x H155 mm - Target Animals: Small animals, birds, reptiles - Power Consumption: 40W - Included: Cover, Ceramic: Pottery No box included. It has an on/off switch. Used for about one winter season. It was used with a separately sold thermostat, so it wasn't always in operation. I removed it and confirmed it works, providing heat without any problems. Please purchase only if you understand that this is a used item. Thank you for looking.
