These filters then make use of hand picked, thouroughly inspected optical glass of the highest quality available and coatings meant to ensure not only maximum reflectivity, but also the durability to last. These glass filters render the sun a natural-appearing orangeish hue, letting you see the sun in the pallet of hues we traditionally associate with the sun. The filter box is foam lined for protection and shock absorption during handling, and is durable enough to store the filter while not in use.
