Resin cast badge / buckle is similar in style to the one seen in the Aquaman film worn by Mera. Badge will have a gold metallic look. The badge is 4.5" x 3.5". If you select finished with backing, there will be a magnet backer on the badge so it can easily be put on and removed without damaging the fabric.
