This is an official “300” Spartan Shield plastic costume accessory. New and never used. It is a dark bronze/gold color with a weathered patina look. It is 16 in diameter and intended for adults or teens, but might be ok for a bigger kid. It is very light and quite easy to carry. This is not made of metal. It does not look like plastic, though! The details and color make it appear realistic. The shield is perfect for Halloween, costume party, theatre, or even cosplay if you are ok with a plastic shield. This is rare and hard to find. We bought it a few years ago but never used it.
