This is a set of four Marukan pet ceramic heaters: one 100W and three 40W. ● Features • Bulb-type heater that radiates infrared rays to gently warm your pet's body. • Emits only a small amount of light, so it won't disturb your pet's sleep. • Special coating on the surface of the heating bulb makes it less likely to break and prevents scattering in case of damage. • Comes with a hook for easy installation. • Cord with a protective coil to prevent pets from accidentally biting it. ⚠️ Does not have an automatic temperature control function. The bulbs included in the 100W (1 piece) and 40W (1 piece) sets can also be used, but they are used items, so it is unknown how long they will last. *Please refrain from purchasing if you are concerned. *Will be wrapped in cushioning material for shipping. No box or instructions included. *Please understand that these are used items before purchasing. *Used for keeping Bengalese finches. They can be used, but we cannot accept returns or refunds, so please ask any questions in the comments. *We are also selling individual items, so please consider those as well.
