This is a shield-up adapter from Nankai Parts. By simply attaching it to a jet helmet (with 3-snap fasteners), you can make fixed shields like bubble shields "movable." The color is "blue." Please check the photos. Please confirm that both the helmet and shield you intend to attach it to have "3-snap fasteners" before purchasing. We do not accept claims due to size differences, so please understand. This product is not subject to discounts, so any comments requesting a discount will be deleted. Thank you for your understanding.
