Dragon Calavera Mike Giant Signature Sunglasses: The Dragon Calavera Mike Giant sunglasses are a collaboration between Dragon Alliance and the world-renowned tattoo artist, Mike Giant. The Calavera Mike Giant Signature sunglasses feature a solid Grilamid thermoplastic material with a Toric lens which has two base curves: one in the horizontal and one in the vertical direction. This allows the lens to better conform to the natural shape of the human face. The lens also has 100% UV protection, so your eyes will be safe and sound against the evil rays of the sun. The Dragon Calavera Mike Giant Signature sunglasses would be a great addition to your collection.
