Thank you for viewing. This is a heater for small birds. Product Name: Yorisoi Heater Maximum Temperature: Approximately 40°C Power Consumption: 18W Perch Size: Approximately 10 x 100mm Heater Size: Approximately 65 x 85 x 130mm I used this when I had Java sparrows 7 years ago. Because I live in a cold region, I quickly bought a warmer heater, so I only used this for about six months. After that, it was stored at home. It can still be used, so I am listing it for sale. Please understand that this is a used item before purchasing. Please note that I plan to ship it compactly by folding the box.
