You're looking at the official Rays Engineering Face Mask Set, the same company that makes Volk Racing wheels and Gram Light wheels.  This kit includes 1 Black Mask and 1 Red Mask.  They're made of 100% polyester mesh and includes an antibacterial pouch case for storing.  Size is standard for adults.  These are limited edition, so once stock runs out there will be no more.

Note: All sales are final on this item.
