These items are planned to be sold as a set. They were used for a hamster. They were only used for one season during the cold months, so the usage period wasn't long. The "Dantotsu" heater was attached to the ceiling of the cage, and the panel heater was attached to the outside bottom of the cage, so the hamster did not have direct contact with them. For safety, the parts that can be wiped have been disinfected. A 100-yen store mesh has been attached to the "Dantotsu" heater on one side to make it easier to attach to the ceiling. Please remove it if you don't need it. Dantotsu M size Far-infrared upper heater. The "Dantotsu" heater uses special insulation and technical ingenuity to increase the radiation effect, radiating over 90% of the heat downwards with powerful wide heating! Also, since it does not use a heat bulb, it has outstanding durability and economic efficiency. Furthermore, it can be used day and night, so a night-time heat bulb is not necessary. ○ M size W250 x H21 x D200mm ○ Stable power consumption: 32W ○ Purchase price: 6800 yen Panel Warmer Temperature setting function, high-tech heater using electronic controlled PTC panel ○ Panel 150 x 180mm Thank you for your consideration.
