This is an external bird heater from SANKO. The box and instruction manual are included. 20W Made in Japan. It's convenient because it can be mounted vertically or horizontally. 【Body Size】 124 x 190 x 25.5 (excluding protrusions) Used for about one season. There is some burning on the surface of the heating element, but there are no noticeable scratches. Of the included parts, the fasteners were difficult to use, so I discarded them and used cable ties. I will include two cable ties! When shipping, the box will be flattened. Please understand that this is a used item.
