Thank you for viewing. This is a Midori Shokai (Rep Japan) DANTOTSU L size. It has been used. Two fasteners are included. I used it with two fasteners in the center. Thank you. Specifications: 57W Size: Width 40 x Depth 25 x Thickness 2.1cm ◼️The following is a product description. For snakes, lizards, turtles, etc. (Suitable for 60-90cm tanks) ・Powerful wide heating that spreads downwards. It warms you to the core of your body. ・A heater for snakes and lizards that may get burned by wrapping around lights. It is ideal for preventing burns. ・For turtles, upper heating is effective because their lungs are located directly under their shells. Other creatures also need to warm the entire cage to breathe warm air and metabolize. ・DANTOTSU increases the radiation effect with special insulation and technical ingenuity, radiating over 90% of the heat downwards. ・You can use a mist sprayer, so it is also ideal for creatures that need humidity. ・Since it does not use a heat bulb, it is overwhelmingly durable and economical. There is no need to worry about the bulb burning out.
