KORDA's Tail Rubber Nano are specially designed to work in conjunction with the Dark Matter Nano Tubing. These tail rubbers have a 1.4mm bore that provides a seamless connection along the thinner Nano Tubing, preventing tangles when fishing at long range. The Nano Rubbers are compatible with all Korda Lead Clips and Inline Leads, helping to build a secure, anti-tangle system. Available in three colors to match the Nano Tubing: Weed, Gravel and Silt, with ten in each pack.
