This is a carbon heater for reptiles. I only tested it once, then put it back in the box and stored it. I will ship it without the box. If you cover the shipping cost, I can ship it with the box. In that case, please comment before purchasing. (+300 yen) ↓↓From the following site↓↓ It quickly delivers radiant heat to the bottom of the cage, keeping pets comfortable. The far-infrared radiation heater "carbon heater" efficiently warms the air, shelters, and bedding in the breeding cage, quickly warming the pet's body. It can be used for both daytime and nighttime, and does not emit light like incandescent heat bulbs, making it the perfect heating device for pets that dislike light at night.
