This is a scratch built Kylo Ren belt buckle from the upcoming Star Wars: The Force Awakens film! It is nearly movie accurate with all dimensions and was meticulously recreated using known measurements and reference photos specifically from the spring Star Wars Celebration event in Anaheim (where the Kylo Ren costume purportedly from the film was displayed).
Buckle measures 2.35" wide x 5" tall x .25" thick.
