Super-Electrified Robot Tetsujin 28 FX Set of Tetsujin 28 and Tetsujin 17 When you insert 4 AAA batteries, it makes sounds and flashes lights. The negative battery spring was damaged, so I replaced it with a new spring. It works. This is an old, used item with peeling stickers, scratches, etc. It will be shipped without the box or batteries. Please refrain from returns. Thank you for looking.
