This is in excellent condition! The Jumpsuit is very well made. It's very thick and it has four name tags. It is a size XL and it doesn't look like it has been worn. It's an official piece.
The Proton pack looks unworn also with bubble wrap in places and no strain on the backpack straps at all. It looks new and is an official, great piece.
The PKE meter is brand new in the package.
This costume will really set you apart with it's quality. Surely it will be in the running for best costume! Great for comic con shows also!
