Review on Enhance Your Halloween Costume: BinaryABC Halloween Costume Accessories by Stuart Sugden

I thought it was some kind of foam or filler but it's a thin piece of material. If it bends I think it will show an obvious crease. It's smaller but I bought it for a 4 year old. I bought this to use as a Halloween costume but also thought it might remain part of a dressing box, due to the thinness I'm not sure how long it will take before it bends or breaks.
