KORDA's Dark Matter Nano Tubing is made from the same materials as the extremely popular Dark Matter Tubing, but with a thinner outer diameter and smaller bore, making the Nano version perfect for long distance casting. Nano Tubing is 30% thinner than the original version, making it smoother and reducing drag when casting. Like its bigger brother, the Nano version is impregnated with tungsten grains, so that it molds to the contours of the soil. With its smaller bore, Nano Tubing can be used with line up to 0.40mm in diameter and is available in three versions: weed, gravel and silt. Supplied in packs of 2m. To complement the Nano Tubing, a Dark Matter Nano Tail Rubber is also available, with a smaller bore and slimmer profile to match the tubing's characteristics.
