TECHNOLOGY: Tippet Rings are small, very strong and lightweight, and make rigging and tippet replacement fast and easy. Tapered leaders last longer with a tippet ring as the leader will not be shortened every time the angler replaces the tippet. Extremely easy to add droppers, and are an excellent choice for European Style Nymphing and for Indicator nymph fishing. Come in two sizes: Trout - 25lb/2mm diameter. Steelhead - 45lb/3mm diameter
