How about this for your cute pet before the cold season? As shown in the photos, this is a set of four SANKO panel heaters in excellent condition, with almost no damage, as they have not been in direct contact with the animals. As of October 19, 2025, purchasing the same items on Amazon would cost approximately ¥24,900 for the set of four, so this is a great deal. Operation has been confirmed (photos of power on available). Purchased on Amazon last January and used under a breeding plastic case placed inside an insulated foam case, so they did not come into direct contact with the animals. These products were used for only one season. These heaters are designed to be placed on the bottom or sides of the cage to create a hot spot. * 32W Dimensions: 240 x 480 * 16W Dimensions: 240 x 240 * 14W Dimensions: 155 x 240 * Temperature settings: 25-45°C (variable) Please feel free to ask if you have any other questions.
