This is for Mars Attack green Brain Disintegrator. It's in the original package. Blue and green box. Still strapped in the box. Never removed. New condition. It still has the batteries inside. They are dead. I had another one of these up that I took out of the box. I put new batteries in it and it worked. There was no leakage from the old batteries. I assume that this one is the same? The gun is approx. 10 inches long. The box is approx. 9 1/4 x 11 1/4 inches. Super cool looking ray gun. Brains above the trigger. See photos for condition.
