... quoting from the "allfishingbuy" site:

"This clear Tippet Material system has a non-reflective finish that makes it nearly invisible under most light and water conditions. Clear is a good choice for all situations such as surface steelhead or saltwater flats fishing. It features many advantages in this class, high strength to diameter ratio, low coil memory, good knot strength and reliability. Coated for abrasion resistance, a great tippet available in 5X, 6X or 7X diameters. Tippet is the thinnest section of Tenkara line system and will need replacing frequently." (emphasis added )
