Sanko Shokai External Bird Heater E55 Made in Japan, 20W I am selling this because it was a little too big for my birdcage. It has been left unopened since purchase, so there are some scratches on the outer box (like the scratches in photo 5). Although it is unused, I tested it for power when listing it. Therefore, although it is unused, I am listing it as "like new." Please check photo 2 for the size. The temperature can be switched between Low and High. The main unit, instruction manual, and mounting hardware are all included.
