This is a replacement 100W ceramic heater bulb from MARUKAN. Brand new, unused. When shipping, I will take waterproof measures and wrap it in a paper bag. Compatible devices: ・MARUKAN Ceramic Heater 100W with cover ・MARUKAN One-touch stand OS-210 ・Any device with an E26 socket. Made of ceramic, it can be used for a much longer time than regular light bulbs. Ceramic construction makes it less prone to breakage and has excellent heat conductivity. Since it emits no light, your pet can sleep peacefully without disrupting their biological rhythm. I use it without a cover, from outside the cage. It can also be used for reptiles and small animals. I have a total of 4. #Reptiles #Pantheon #Rabbit #Ferret #Parrot #HeatingEquipment
