to help my fellow collectors out!!! PVC reacts to acetone, so if you own nail polish remover that contains acetone, rub a soaked cotton pad over the sleeve. if it gets cloudy or starts melting : PVC
if it doesn’t react : NOT PVC
CPP/PP doesn’t react to acetone. hope that helps!!
As originais tem esse selo, a diferença tá no material. Geralmente falsas tem pvc o que estraga o card a longo prazo, mas se não tiver na composição é ok usar
